All You Need To Know About Internal Tremors

Internal tremors feel like vibrations that happen inside the body. They often occur without any visible movement, but you can feel them. They produce a quivering sensation inside a person’s arms, legs or abdomen. 

For example, a person won’t shake physically while writing or pouring tea. They are different from vertigo, another symptom of a neurological condition that characterizes itself with the feeling that the world around you is spinning. 

Internal tremors, also known as internal vibrations, are not life-threatening; they are majorly seen in people suffering from Parkinson’s disease, multiple sclerosis and essential tremor. 

Because they are invisible, they may be difficult to explain to the doctor. In this article, we look at the causes of internal tremors and how to stop them.

Causes Of Internal Tremors

Nervous system disorders like Parkinson’s disease (PD), multiple sclerosis (MS), or essential tremor (ET) can cause internal tremors. A study showed that about 33 percent of people with Parkinson’s disease experienced internal vibrations, while about 55 percent of people with ET experienced internal tremors. About 36 percent of people with multiple sclerosis reported feeling the same too. 

Anxiety and stress can also cause or worsen tremors. People who experience tremors feel other sensory symptoms like tingling, aching, and burning. These symptoms give an idea of the exact condition a person has. 

Tremors are majorly caused by damage in one’s brain, affecting the nerves that control the muscles. Below is information about PD, MS and ET, the three most common causes of internal tremors:

Parkinson’s Disease

A loss of dopamine-producing brain cells causes this neurological condition. It’s common in older people, above 60years, and they may experience the following symptoms:

  • Stiff muscles which make it difficult to move

  • Quiet or hoarse voice

  • Loss of sense of smell

  • Dizziness

  • Slow and shuffling movements

  • Poor coordination and balance

  • Constipation

These symptoms don’t appear at once; they may progress quickly or slowly. Some may start from one limb and move to another.

Multiple Sclerosis (MS)

This is also another condition that affects the central nervous system. In multiple sclerosis, the immune system attacks the body’s nerves.

Symptoms are often seen in persons aged 20-40 and can affect any body part. 

  • Difficulty with speech

  • Pain

  • A sensation of numbness or pins and needles

  • Poor coordination and balance

  • Color blindness or blurred vision

  • Fatigue

  • Weakness

Essential Tremor (ET)

This is one of the most popular causes of internal tremors. It is associated with the degeneration of the cerebellum, the section of the brain that receives information that regulates a person’s balance and movement. The cerebellum receives it from the spinal cord and other sensory body parts.

Accompanying symptoms of essential tremor is an uncontrollable movement known as a hand tremor. The tremors may also affect the head, tongue, limbs, trunk, and speaking ability.

The following are triggers of essential tremors:

  • Stress and anxiety

  • A low blood glucose level

  • Fever

  • Heightened emotions

Internal tremors from essential tremor usually start from one hand and progress to the other.

How To Stop Internal Tremors

There are no diagnostic tests for internal tremors, and the causes may overlap, from lifestyle choices to PD and other neurological conditions. However, anyone experiencing muscle weakness, tingling sensation, or poor coordination should consult a doctor for a proper diagnosis and possible treatment.

Because the causes of tremors are similar to that of other neurological disorders, doctors may recommend treatment or supplements to reduce the incidence of these vibrations and tremors. The symptoms may also vary from one person to another, and some persons may not need treatment. 

If the internal tremors are caused by Parkinson’s disease, multiple sclerosis, and essential tremor, doctors will aim to treat the underlying condition. 

Some of the possible ways to treat internal shaking include the following:

Reduce Stress And Anxiety

Experts say stress and caffeine can cause internal tremors to increase. Stress causes muscle tension which intensifies tremors. Sleep more and find what helps reduce stress. This will help minimize internal tremors. For better relaxation, engage in meditation practices, daily workouts, and practice breathing/relaxation techniques.

Avoid Caffeine And Other Stimulants

Most people take caffeine and other stimulatory drinks to stay alert. However, caffeine can cause a jittery effect on the body. People suffering from essential tremor should avoid caffeine as it can increase internal vibrations. Because caffeine stimulates people's “fight or flight” response, it can increase anxiety and cause panic. So, if trying to reduce internal tremors, it’s safe to steer clear of caffeine, energy and sugary drinks.

Physical Therapy

Working with a physical therapist can help with gaining muscle control and learning to strengthen the muscles. Physical therapy also involves behavorial relaxation therapy to reduce the severity of the tremors. With behavioral relaxation, the patient is relaxed to reduce stress and the severity of internal shaking. 

Adaptive/Assistive Devices

These devices help to reduce internal shaking so people can perform basic tasks. Example of adaptive devices is wide-grip pens and eating utensils which helps to reduce internal tremors. A great device for hand tremors associated with ET and Parkinson’s disease is the Steadi-Two, a wearable glove which helps reduce trembling/shaking.


The treatment administered for internal tremors depends on the underlying condition. Drugs may treat internal tremors caused by Parkinson’s disease like ropinirole or pramipexole. These drugs increase the dopamine level in the brain or mimic the effects of dopamine. 

Beta-blockers or antiseizure drugs often treat internal tremors caused by essential tremor. The drugs for multiple sclerosis depend on the progression of the condition. Steroids may be administered for internal tremors resulting from multiple sclerosis. 


Most people can experience internal shaking several times a day, a discomforting condition which can interfere with daily activities. The major causes of internal tremors are Parkinson’s disease, multiple sclerosis, and essential tremor. So, administering similar treatment for any of them may cause internal tremors to stop.

However, the fact that you experience shaking inside doesn’t mean that you have any of the above-listed neurological conditions. 

Your internal tremors could be a result of stress or dietary stimulants. So, undergo some lifestyle changes by avoiding caffeine and stimulating drinks.

If you’re experiencing internal tremors and want to learn how to stop internal tremors, consider seeing a doctor to discuss any accompanying symptoms and possible causes.
