Index finger twitching: 11 major causes and treatment

What is Index finger twitching?

So out of the ordinary, your fingers start moving side to side, that movement is called a twitch, and sometimes for no apparent reason our index finger twitches.

A twitch is a small, involuntary muscle contraction and relaxation. “Fasciculations” are the medical term for twitches, and they can occur in any muscle area, including the fingers. People with finger twitching may be worried that a neurological disorder is developing.

However, when other symptoms do not accompany this twitching, it is usually not a cause for concern. Physical exercise, fatigue, and drinking too much caffeine can cause or worsen index finger twitching. This article explores the causes of finger twitching and its treatments.

The twitching of the Index finger and other fingers may seem disturbing, but it is often a benign sign. Many cases result from stress, anxiety, or strain of the muscle. Twitching of fingers and muscle spasms may now be more prevalent than ever, as texting and gaming are such popular activities. While most cases of twitching of the index finger are mild, some instances may be an indication of a severe nerve or motion disorder.

Causes of Index finger twitching?

The twitching of the index finger is a sign that may be caused by several factors or disorders. Common factors that may trigger involuntary spasms of the finger or twitching include:

  1. Muscle fatigue
  2. Vitamin deficiency
  3. Certain medications like isoniazid, corticosteroids, e.t.c.
  4. Dehydration
  5. Benign fasciculation syndrome
  6. Carpal tunnel syndrome
  7. Parkinson’s disease
  8. Essential tremor
  9. Lou Gehrig’s disease
  10. Hypoparathyroidism
  11. Tourette syndrome
  • Muscle fatigue

Overuse and strain of the muscle are common factors that can cause twitching of the fingers. When you function primarily with your hands regularly clicking on a keyboard, playing a lot of video games, or even spending time texting. Consequently, you may feel muscle tiredness that can result in your index finger twitching, as well as other fingers twitching.

  • Vitamin deficiency

A lack of nutrients may influence the working of your muscles and nerves. You can feel your index finger and hand twitching if you are deficient in potassium, vitamin B, or calcium.

  • Certain medications

Muscle twitching and spasms can be side effects of some medication including:

  • antibiotics such as isoniazid
  • Corticosteroids
  • Drugs that interrupt calcium movement such as flunarizine
  • Medications used in treating epilepsy, such as topiramate
  • Muscle relaxant, such as succinylcholine
  • Psychiatric medication e.g., lithium

If a person thinks a drug causes twitching of the muscle, they should talk to their doctor before stopping treatment. If possible, the doctor may recommend lowering the dosage or switching to an alternative medication.

  • Dehydration

To retain optimum health, your body needs to stay properly hydrated. Water intake assures the correct response of your nerves and that you maintain a normal electrolyte balance. Dehydration can be a factor in muscle spasms and index finger twitching.

  • Benign fasciculation syndrome

Those with benign fasciculation syndrome (BFS) experience frequent involuntary muscle twitches. Signs are usually present for years, and some doctors only treat BFS if there have been signs for at least five years. Doctors do not know what causes BFS. However, one study in 2013 found a link between this syndrome and reduced neurological activity of the small nerve fibers in the sweat glands and skin. It will require more research to confirm this relationship.

  • Carpal tunnel syndrome

This condition causes numbness, tingling, and muscle spasms in your fingers and hands. Carpal tunnel syndrome occurs by applying pressure to the wrist’s median nerve.

  • Parkinson’s disease

Parkinson’s disease is a condition that causes a progressive neurodegenerative disorder that affects motion. While tremors are normal, it can also cause body weakness, writing disorders, and changes in speech

  • Essential tremor

Repeated, involuntary movement of a part of the body is known as essential tremor. The movements occur with consistent frequency and force in a person with essential tremor. Essential tremor is the most popular neurological cause of tremors, but doctors do not know what causes the condition.

People usually feel essential tremor in their hands. The tremor extends to the head in some people, and it can also affect the voice of a person. Essential tremor does not change the life expectancy of a person. But, it can affect the quality of life of a person and trigger disabilities.

  • Lou Gehrig’s disease

This disease is also known as amyotrophic lateral sclerosis (ALS), a nervous disorder that destroys your nerve cells. Although the twitching of the muscle is one of the first symptoms, it can lead to fatigue and total disability. For this illness, there is no treatment.

  • Hypoparathyroidism

This rare condition causes the body to secrete parathyroid hormone levels that are unusually low. This hormone is essential to maintain the calcium and phosphorous balance of your body. If hypoparathyroidism is suspected, you can suffer, among other signs, muscle aches, twitching, and fatigue.

  • Tourette syndrome

Tourette is a tic disorder marked by repeated motions and vocalizations involuntarily. Twitching, grimacing, sniffing, and shoulder shrugging are some of the typical tics.

Treatment for index finger twitching

Index finger twitching often resolves itself on its own. If your symptoms persist, however, it is best to schedule your doctor’s visit to discuss a potential treatment plan. Ultimately, treatment depends on the underlying cause. Standard options for treatment include:

  • Physical therapy
  • Prescribed medication
  • Splinting or bracing
  • Psychotherapy
  • Deep brain stimulation
  • Steroid or botox injections
  • Surgery

In Conclusion

Your index finger twitching is not a life-threatening symptom, but it may indicate a more severe medical condition. However, never self diagnose yourself. When you start experiencing persistent twitching of your index finger and other fingers followed by other unusual signs, plan a doctor’s visit.

Usually, the person may undergo further signs and symptoms if finger twitching results from a neurological disease. Early detection and proper diagnosis will ensure the best treatment for your symptoms.
