Causes and treatment for internal vibrations (internal tremors)



Internal movements, also known as internal tremors, can affect individuals with Parkinson’s llldisease , multiple sclerosis, or severe tremor. Internal tremors are not dangerous but they can be alarming and interfere with the daily life of a person.

Internal tremors are sensations of shaking which are felt inside the body. They take place without visible movement which causes) ll tremors.

An person can experience internal tremors in the trunk, arms , legs or internal organs.

In this article we look at the causes of internal tremors and their treatment.


Internal tremors can occur in the trunk or the limbs.
Internal tremors can occur in the trunk or the limbs.

People with Parkinson’s disease ( PD), multiple sclerosis (MS), or essential tremor (ET) may experience internal and external tremors.

The causes of internal tremors are not well known, and there is minimal research under way. Doctors prefer to assume, however, that these tremors derive from the same neurological causes as external tremors.

A 2017-issued study found a correlation between tremors and social anxiety. Some researchers have also indicated that internal tremors may cause too slight physical movement to detect.

Authors of a 2016 study indicated early, irregular signs of movement disorders, including PD, are internal tremors. Other researchers indicated that everyone may experience internal tremors but they’re more pronounced in people with PD, MS, and ET.

Learn more on PD, MS, and ET, the three most common causes of internal tremors.

Parkinson ‘s disease

PD is a neurological disorder which results from the loss of brain cells producing dopamine. Typically it happens in people over the age of 60.

People who have PD may have any of the following symptoms:

  • slowness of movement
  • external tremors, including visible trembling in the hands, limbs, face, and jaw
  • internal tremors
  • stiffness of the arms, legs, and trunk
  • poor coordination and balance

These symptoms can develop rapidly or slowly, and can complicate everyday activities. Tremors are not often the most noticeable symptom of PD but there are tremors in many people with the disease.

An individual can initially only experience a tremor in a single limb. The tremor can spread to both sides of the body as the condition progresses. Stress and strong emotions can trigger tremors.

Treatments for PD

PD can not be cured. It is a chronic condition which develops over time. There are also a variety of recovery choices.

A doctor can prescribe a combination of levodopa and carbidopa to replenish the supply of dopamine within the brain. This will assist in the treatment of advanced PD.

Other choices relating to medications include bromocriptine, pramipexole, and ropinirole.

For people who do not respond to the drug, a doctor may suggest surgery. The primary type is Deep Brain Stimulus (DBS).

A surgeon inserts electrodes in a person’s brain during the process of the operation. These activate targeted areas to soothe certain PD symptoms. DBS can also minimize the need for some medications and this can be particularly helpful for people with adverse side effects.

Multiple sclerosis (MS)

Damage to the nerves characterizes multiple sclerosis.
Damage to the nerves characterizes multiple sclerosis.

MS is a chronic disorder which affects the central nervous system.

Many experts believe that in a person with MS, the immune system attacks and damages the body ‘s nerves.

This can influence many parts of the body, and can have an important effect on the quality of life of an individual.

MS symptoms usually develop between age 20 and age 40. Might include:

  • blurred or double vision
  • color blindness
  • blindness in one eye
  • muscle weakness
  • poor coordination and balance
  • a sensation of numbness or pins and needles
  • pain
  • speech difficulties
  • internal and external tremors
  • dizziness

Around half of the people with MS also experience difficulty with:

  • memory
  • attention
  • concentration
  • judgment

A person may also experience tremor.

Treatment of MS

Currently there is no remedy for MS, and its severity varies between individuals.

Disease-modifying therapies (DMTs)

In the past, doctors found MS untreatable but the outlook is changing with new medications and treatment choices.

Current American Academy of Neurology (AAN) guidelines encourage physicians to begin administering a type of drug known as disease-modifying therapy (DMT) as soon as possible after a diagnosis.

These drugs tend to decrease the number of flares a person experiences in relapsing-remitting MS (RRMS) with early use, and they may delay the disease progression.

Examples include:

  • injectable interferon beta-1a and 1-b, such as Avonex and Extavia
  • injectable glatiramer acetate, for example, Copaxone and Glatopa
  • oral medications, such as siponimod (Mayzent) and fingolimod (Gilenya)
  • infusions, including alemtuzumab (Lemtrada) and ocrelizumab (Ocrevus)

Mitoxantrone is an older DMT that can have significant adverse reactions. A doctor will prescribe this only if a person has severe symptoms, and if the potential benefits outweigh the individual’s risks.

Anyone who has been using mitoxantrone for some time should ask their doctor about newer and more powerful medications.

Flares and symptoms

A person will take a DMT at regular intervals, whether or not they experience a relapse.

When flares occur, a doctor may prescribe:

  • steroid injections to reduce inflammation and help manage severe symptoms
  • specific medications to help with specific symptoms, such as weakness and muscle spasms

A doctor may prescribe muscle relaxers or tranquilizers for people with sustained muscle stiffness and spasticity.

Treatment for tremor

Drugs to help relieve tremor include:

  • isoniazid, for example, Laniazid or Nydrazid
  • clonazepam, for instance, Klonopin, Rivotril or Syn-Clonazepam

Non-drug therapies

It can also aid in exercise, occupational therapy, and physical therapy. A physician may advise on an exercise plan that fits the needs of a person.

They can also advise on aid aids, such as a walking cane, that may help.

MS symptoms and development differ greatly among individuals. Each person with their doctor will draw up a treatment plan to meet their needs.

Essential tremor

ET is the most prevalent form of anomalous tremor.

Often the disorder is associated with some of the cerebellum having mild degeneration. This is the part of the brain that gets the knowledge needed to control the quality of the movements of an individual.

The cerebellum gets this input from other parts of the brain, the spinal cord and the sensory systems of the body.

People with ET can experience involuntary, rhythmic movements, most frequently a tremor in the hand. Also, the tremor can affect the head, tongue, limbs, trunk and ability to talk.

Symptoms can occur at any age but are usually noticeable in people over 40 years of age. ET Causes can include:

  • stress and anxiety
  • heightened emotions
  • fever
  • feeling physically tired
  • low blood sugar

The tremor usually occurs on both sides of the body but in the dominant hand it is always more apparent.

Treatment of ET

Although there is no cure for ET, medicines will help to reduce the symptoms. This may involve anticonvulsants or beta-blockers.

Some people who have ET find physical , occupational, and DBS therapy beneficial. Plans for treatment often include reducing stimuli including caffeine and other stimulants.


A doctor will prescribe treatment for internal tremors according to the cause.
A doctor will prescribe treatment for internal tremors according to the cause.

There are no diagnostic tests currently available on internal tremors. Anyone who feels a tingling feeling, trembling, muscle weakness or impaired coordination should talk to a doctor, however.

Doctors may prescribe therapies similar to those for other movement or neurological conditions for individuals with internal tremors.

However, the severity of internal tremors can vary from person to person and some may feel there is no need for treatment.

If the internal tremors are caused by PD, MS, or ET, doctors may try to treat the underlying condition.

Treatments for internal tremors can include:

  • reducing anxiety and stress
  • avoiding dietary stimulants, such as caffeine
  • avoiding intense exercise and heat

Doctors may prescribe DBS or medicines similar to those for PD, MS, and ET for some people.


Although there are no dangerous internal tremors, they may be disconcerting and can interfere with everyday activities.

The most common causes of internal tremors include PD, MS, and ET. For certain people tremor therapies for these neurological disorders may be identical to therapies.

And it can help to prevent recognized stimuli such as stress or stimulants.

Immune System / Vaccines

Concussion in adolescents linked to an increased chance of developing MS later in life



A recent study finds that people who get a concussion as teenagers are more likely to acquire multiple sclerosis later in life.

A concussion is a type of traumatic brain injury (TBI) that is caused by a quick impact or shock to the head and can impair brain function.

Loss of consciousness, dizziness, impaired balance and coordination, changes in behavior and mood, memory issues, and confusion are all signs and symptoms of a concussion. Symptoms usually occur within a few days of a head injury, although they might take up to a week.

While concussion symptoms are generally temporary, research has recently revealed that head trauma can have long-term consequences for brain health.

brain concussion

Researchers have now discovered a relationship between adolescent concussion and the chance of developing multiple sclerosis (MS) later in life.

Prof. Scott Montgomery of Sweden’s Oerebro University and colleagues published their findings in the Annals of Neurology recently.

MS is a neurological disease that affects around 2.3 million people worldwide.

An aberrant immune reaction is thought to be the cause of the condition, in which the immune system assaults and destroys myelin, a fatty material that protects nerve fibers in the central nervous system.

Prof. Montgomery and colleagues identified 7,292 MS patients using data from the national Swedish Patient and Multiple Sclerosis registries. All of the participants were born between 1964 and 2012, and MS diagnoses were made between 1964 and 2012.

Each MS patient was matched with ten people who did not have MS on the basis of sex, year of birth, age at MS diagnosis, and location of residence. In all, 80,212 people took part in the survey.

The researchers also looked for any concussion diagnoses among the subjects during childhood (between the ages of birth and ten years) and adolescence using data from the Swedish Patient Register (between the ages of 11 and 20 years).

MS risk increased more than twofold

The researchers discovered no link between childhood concussions and the chance of developing MS later in life.

Participants who had one concussion in adolescence were 22 percent more likely to get an MS diagnosis later in life, whereas those who had more than one concussion were more than twice more likely to have MS later in life.

According to previous study, head trauma can trigger an aberrant immune response that harms the brain. This procedure, according to the authors, might explain their findings.

“Head trauma in adolescence, particularly if repeated, is associated with a raised risk of future multiple sclerosis, possibly due to initiation of an autoimmune process in the central nervous system.”

“Another reason to protect adolescents against brain damage, particularly if they are at risk of repetitive trauma, such from sports-related injuries,” adds Prof. Montgomery.

According to the Centers for Disease Control and Prevention (CDC), concussion or another type of TBI was diagnosed in roughly 329,290 people in the United States who were treated for sports or recreational injuries in 2012.

Why do my legs and feet feel numb?



Due to sitting in a position that exerts too much pressure on the nerves or restricts blood flow, a person may have numbness in their legs and feet. Long-term or inexplicable numbness, on the other hand, might indicate an underlying medical condition.

Conditions including multiple sclerosis (MS), diabetes, peripheral artery disease, and fibromyalgia can cause long-term numbness or tingling in the legs and feet. The feeling might be felt across the leg, below the knee, or in various parts of the foot.

In this post, we’ll look at some of the causes of numbness in the legs and feet, as well as the symptoms and treatments available.


feet Numbness

Numbness is just one of the many symptoms connected with numbness, whether momentary and chronic.

Many people who have numbness in their legs and feet often have other symptoms that occur at the same time or in waves, such as:

  • tickling
  • itching
  • a crawling feeling under the skin
  • tingling
  • burning


Because of their position, a person’s legs frequently go numb. Chronic or long-term numbness in the feet and legs, on the other hand, is usually always an indication of a medical condition.

The following are some of the conditions that might cause numbness in the feet and legs:


The most common cause of transient numbness in the legs and feet is poor posture that puts pressure on nerves or reduces blood flow in the lower limbs. The medical word for transitory (temporary) paresthesia is what many people refer to when their leg “falls asleep.”

The following habits might lead the feet and legs to fall asleep:

  • sitting on the feet
  • wearing pants, socks, or shoes that are too tight
  • sitting or kneeling for long periods
  • crossing the legs for too long

Multiple sclerosis

Sensory nerve loss causes numbness in a small area of the body or across the limbs in people with multiple sclerosis (MS). Although MS-related numbness usually only lasts a short time, it can be severe enough to be debilitating.

Stokes and mini-strokes

Strokes and mini-strokes can harm the brain, altering how the mind perceives and processes nerve impulses. A stroke or mini-stroke can result in numbness in various parts of the body, which can be brief or long-term.


Diabetic neuropathy is a kind of nerve injury that occurs in some people. Diabetic neuropathy can result in numbness, tingling, and discomfort in the feet, as well as the legs if the condition is severe.


Nerves in the trunk, spine, hips, legs, ankles, and feet can be compressed, causing numbness in the feet and legs.

Tarsal tunnel syndrome

Tarsal tunnel syndrome is caused by a compressed, pinched, or injured nerve that goes down the back of the leg, along the inside of the ankle, and into the foot.

On the inside of the ankle, the tarsal tunnel is a tiny space. Numbness, burning, tingling, and shooting pain in the ankles, heels, and feet are common people of tarsal tunnel syndrome.

Lower back issues and sciatica

Compression of the nerves leading to the legs can be caused by problems in the lower back, such as a breakdown or herniation of spinal discs, resulting in numbness or sensory difficulties.

Sciatica is a condition in which the sciatic nerve, which travels from the lower back to the legs, is irritated. A person may have numbness or tingling in their legs or feet if this nerve becomes inflamed or constricted.

Tumors and other non-cancerous growths

Tumors, cysts, abscesses, and benign (non-cancerous) growths can push against the brain, spinal cord, or any part of the legs or feet. This pressure can cause numbness in the legs and feet by restricting blood flow.

Peripheral artery disease

The peripheral blood arteries in the legs, arms, and stomach constrict as a result of peripheral arterial disease (PAD), limiting the volume of blood they can pump and lowering blood flow. One of the most prevalent parts of the body affected by PAD is the legs.

When walking or moving upstairs, most people with PAD suffer discomfort and tightness in their legs and hips. Leg numbness and weakness are also common people of PAD.

PAD symptoms usually subside after a few minutes of relaxation.


Fibromyalgia is a chronic or long-term condition that causes widespread pain, aching, and soreness throughout the body. Numbness and tingling in the hands and feet are also common people of fibromyalgia.

The majority of people who have fibromyalgia have a range of symptoms, including:

  • memory problems and difficulty thinking clearly, sometimes called fibro-fog
  • restless leg syndrome
  • stiffness and soreness for no apparent reason, especially in the morning or after sleeping
  • chronic exhaustion

For at least 3 months, almost everyone with fibromyalgia has symptoms in more than one section of their body. Fibromyalgia is unlikely to be the cause of numbness in the legs and feet if it is not accompanied by other symptoms or is not long-term.

Use of alcoholic beverages

Alcohol’s toxins can induce nerve damage, which can lead to numbness, especially in the feet.

Nerve damage caused by chronic or heavy alcohol intake can also induce numbness. Reduced levels of B vitamins, such as B-1 (thiamine), B-9 (folate), and B-12, are connected to nerve damage induced by heavy alcohol consumption.


The best way to treat numb legs and feet is to figure out what’s causing them.


Long-term numbness in the legs and feet can be treated with the following medications:

  • Gabapentin and pregabalin. Medications that block or modify nerve signals may assist to alleviate numbness caused by fibromyalgia, MS, and diabetic neuropathy.
  • Corticosteroids. Some corticosteroids can assist with persistent inflammation and numbness caused by diseases like MS.
  • Antidepressants. Duloxetine and milnacipran are two antidepressants that have been authorized for the treatment of fibromyalgia.

Home remedies

The following are some home treatments for numbness in the legs and feet that may help:

  • Epsom salt baths. Magnesium, a component found in Epsom salts, is believed to improve blood flow and circulation. Epsom salts may be purchased over the internet.
  • Stress management and mental strategies. People with persistent numbness, such as MS and fibromyalgia, should attempt to concentrate on the fact that the numbness is typically transient and will go away on its own. The symptoms of central nervous system disorders are also exacerbated by stress.
  • Rest. Nerve pressure is one of the most common causes of leg and foot numbness, and usually improves with rest.
    Ice. Ice can aid in the reduction of edema that puts pressure on nerves. Several times a day, apply cold compresses or wrapped icepacks to numb legs and feet for 15 minutes at a time.
    Heat. Heat can assist release tight, painful, or strained muscles that might produce numbness by putting pressure on nerves. Overheating numb legs and feet, on the other hand, can exacerbate inflammation and produce discomfort and numbness.
  • Sleep. Many chronic illnesses that cause numbness in the legs and feet have been shown to worsen when people don’t get enough sleep.
  • A nutritious and well-balanced diet. Nerve damage caused by malnutrition, particularly vitamin B deficiency, can result in numbness. Chronic inflammation and discomfort, which can produce numbness, can be reduced by getting adequate vitamins and other minerals.
  • Reduced or complete abstinence from alcohol. Toxins found in alcohol can induce nerve damage and numbness. Alcohol can also exacerbate the symptoms of chronic pain and inflammatory disorders, as well as create flare-ups.
  • Massage. Massage can assist enhance blood flow and alleviate discomfort in numb legs and feet.
  • Exercise. A lack of activity can cause the heart and blood arteries to weaken, limiting their capacity to pump blood to the lower limbs. Yoga, Pilates, and tai chi are examples of activities that help improve blood flow and relieve chronic inflammation or discomfort.
  • Supportive devices. Nerve pressure caused by injuries, tarsal tunnel syndrome, or flat feet can be relieved using braces and specially tailored footwear.

Alternative therapies

Alternative remedies have been demonstrated to help alleviate the symptoms of numbness in the legs and feet caused by several diseases. The following therapies are available:

  • hydrotherapy
  • mindfulness meditation
  • guided imagery
  • vitamin B supplementation (especially B-3, B-6, and B-12)
  • massage
  • reflexology
  • acupuncture
  • biofeedback

When to see a doctor

Consult a doctor if you have numbness in your legs or feet that:

  • lasts for long periods
  • is accompanied by permanent or long-term changes in the color, shape, or temperature of the legs and feet
  • is not related to postural habits or lifestyle factors, such as tight clothing and footwear
  • is accompanied by any other chronic symptoms


Numbness in the legs and feet is a frequent problem, but if it persists, it might indicate an underlying medical condition.

Anyone who has unexplained numbness that is persistent, frequent, severe, debilitating, or accompanied by other chronic symptoms should consult a physician for a diagnosis and treatment options.

What you should know about MS-related walking issues, including how to test and treat them



Multiple sclerosis (MS) is a central nervous system illness that affects people. It can restrict mobility, making it difficult to walk.

According to the National MS Society, the disease affects around 1 million people in the United States. One of the most prevalent mobility-related symptoms is difficulty walking.

This post discusses how MS can damage one’s ability to walk, the mobility tests used by physical therapists, and the many therapies available.

MS walking difficulties

MS walking difficulties

The central nervous system, which includes the brain, spinal cord, and optic nerves, is affected by MS. Damage to this system, which controls how a person moves and reacts to stimulus, might result in mobility issues.

An immune system problem in a person with MS causes the immune system to attack healthy tissue, in this case myelin.

A fatty substance that covers and insulates nerve fibers is known as myelin. It also aids in the rapid transmission of signals via the neurons.

If myelin is injured or destroyed, the nerve it protects may lose its ability to receive impulses correctly. This means that messages traveling through the nerve may be disrupted or never reach their destination.

MS-related movement difficulties are thought to be caused by myelin loss in the cerebellum, according to experts. The cerebellum is a part of the brain that aids with movement and coordination.

These mobility issues may include:

  • muscle tightness, stiffness, or spasms
  • problems with balance
  • severe numbness in the feet
  • loss of position sense, which involves knowing where the feet are when walking
  • fatigue
  • muscle weakness
  • trouble with vision
  • cognitive issues
  • unstable walking

Gait changes due to MS

The gait of a person is their walking pattern. According to a 2018 study, 50–80 percent of people with MS suffer balance and gait problems.

Other research from 2018 reports a range of gait alterations, including:

  • a slow walking speed
  • a reduced range of motion in the leg joints
  • a smaller step length
  • reduced stability
  • difficulty lifting the front part of the foot, which is called “foot drop”

Gait issues can increase the risk of falling. According to the National MS Society, 50–70% of people with MS experienced falls in the two–six months before to taking the survey.

MS walking tests

A person with MS may be asked to take a walking test by a physical therapist. This entails walking a predetermined distance while the therapist assesses their gait.

The findings may aid physical therapists in more successfully treating gait disorders.

Timed 25-foot walk

This requires a 25-foot walk (ft). A person should walk as swiftly as they feel comfortable, and assistive aids such as a cane may be used.

The person’s physical therapist will time them while they walk to a distance marker and, possibly, as they return. The purpose is to assess the person’s gait speed, which is a useful indicator of walking ability.

Ambulation index

This is comparable to the timed 25-foot walk test, which has mostly supplanted it.

Walking 25 feet as quickly as possible while being timed is also part of the ambulation index. The purpose is to quantify mobility rather than gait speed in this case.

A person’s score ranges from 0 to 10. They have a score of 0 if they are totally active, and a score of 10 if they are unable to get out of bed.

Dynamic gait index

This entails assessing a person’s walking style, as well as their balance and potential for falling.

To complete this test, a person must walk and perform additional activities, such as:

  • changing speed
  • turning their head left and right or up and down
  • avoiding obstacles
  • turning on the spot
  • climbing stairs

The 12-item MS walking scale

This questionnaire, often known as the MSWS-12, contains 12 statements about how MS affects one’s ability to walk.

The person being tested will be asked to rate each statement on a scale of 1 to 5 by the healthcare expert administering the test.

A “1” indicates that the person has not had the experience described in the statement. A score of 5 indicates that they have had a particularly bad experience with it.

Timed up-and-go test

This is how physical therapists time how long it takes a person to get out of a chair, walk 10 ft, and then return to the chair.

According to the Centers for Disease Control and Prevention (CDC), if it takes more than 12 seconds, the person is at risk of falling.

Treatment options and self-management techniques

Physical treatment, according to the National MS Society, can help with a variety of gait issues.

To assist a person adapt, a physical therapist may propose vestibular activities that cause imbalance. These activities could include:

  • head or eye movements
  • altering visual input
  • walking on different kinds of surfaces

They may also encourage a person to do stretching exercises to improve:

  • flexibility
  • strength
  • cardiovascular fitness
  • balance
  • coordination
  • relaxation

Some prescription drugs can enhance a person’s gait by reducing muscular stiffness and speeding up walking.

People with MS may benefit from a variety of assistive equipment, such as canes, crutches, or braces.

Anyone who has difficulty walking should get medical advice on how to lessen their risk of falling. This could entail:

  • not wearing high heels
  • avoiding slippery surfaces
  • removing obstacles and trip hazards from the home
  • keeping walking areas well lit, especially at night


MS can make it difficult for nerves to transmit electrical signals as they should. This can lead to mobility issues, such as difficulty walking.

Physical therapists employ a variety of tests to determine how MS affects a person’s gait and to improve treatment options.

Stretching and exercising, as well as utilizing assistive equipment and maybe taking drugs, can all help with mobility issues. Anyone with MS who is having trouble walking should speak with a member of their medical team.
