A twitch refers to a slight, voluntary contraction or relaxation of a muscle group or muscle group. Fasciculations are the medical term for finger twitching. They can occur anywhere there are muscles, even in the fingers.
Finger twitching can be a sign that someone is developing a neurological disorder. It is not usually a sign of a neurological disorder if the twitching doesn’t occur with other symptoms.
Muscle twitching can be caused by physical exertion, fatigue, or excessive caffeine intake.
We will be discussing nine causes and possible treatments for finger twitching in this article. We offer guidance on when to visit a doctor.
Although finger twitching can seem alarming, it is often a benign symptom. Many cases can be attributed to stress, anxiety, and muscle strain.
Because texting and gaming are so popular, finger twitching may be more common than ever.
Although finger twitching can be mild in most cases, it could indicate a more severe nerve disorder or movement disorder.
What causes finger twitching
There are many possible causes of finger twitching. Involuntary finger spasms and twitching can be caused by the following:
- Muscle fatigue. Finger twitching can be caused by overuse or muscle strain. Finger twitching can occur if you use your fingers a lot, work primarily with your hands, text a lot, or type on the keyboard.
- Vitamin deficiency. A lack of certain nutrients can cause nerve and muscle dysfunction. Low levels of calcium, vitamin B, and potassium can cause finger and hand twitching.
- You can get dehydrated. To maintain optimal health, your body must be adequately hydrated. Hydration is essential to ensure that your nerves are functioning correctly and have a healthy balance of electrolytes. It is a crucial factor in preventing muscle spasms and finger twitching.
- Carpal tunnel syndrome. This condition can cause numbness, tingling, and muscle spasms. Carpal tunnel syndrome is caused by pressure being applied to the median nerve at your wrist.
- Parkinson’s disease. Parkinson’s disease, a progressive neurodegenerative disorder that can affect your movement, is called Parkinson’s. Although tremors are typical in Parkinson’s disease, they can also cause writing disabilities, speech problems, and bodily stiffness.
- Lou Gehrig’s Disease. It is also known as amyotrophic lateral sclerosis or ALS, a nerve disorder that causes the death of your nerve cells. Although muscle twitching may be the first sign, it can lead to weakness and total disability. This disease is incurable.
- Hypoparathyroidism. Hypoparathyroidism is a rare condition that causes your body’s production of low levels of parathyroid hormone. This hormone is vital for maintaining the body’s calcium and phosphorus balance. Hypoparathyroidism can cause weakness, muscle aches, twitching, and other symptoms.
- Tourette syndrome. Tourette syndrome disorder causes involuntary repetitive movements or vocalizations. Twitching, grinning, sniffing and shoulder shrugging are some of the most common symptoms.
What can you do to treat finger twitching?
Sometimes, finger twitching will resolve on its own. If you’ve symptoms, you ought to consult your doctor. Doctors will help you determine a treatment plan.
The root cause of the problem will determine how the treatment is done. There are several standard treatment options:
- Prescribed medication
- Physical therapy
- Bracing or splinting
- Botox or steroid injections
- Deep brain stimulation
1. Certain medications
Some medications can cause finger twitching.
Muscle twitching can be a side effect of some medications, including:
- Isoniazid, An Antibiotic
- Flunarizine is a drug that interrupts the movement of calcium
- Topiramate is a drug that helps treat epilepsy
- Lithium is a Psychiatric Medication
- Succinylcholine, A Muscle Relaxant
Before stopping a medication that causes muscle twitching, a patient should consult their doctor.
If possible, the doctor might recommend that you lower your dosage or switch to another medication.
2. Magnesium deficiency
Magnesium deficiency can cause muscle cramps or tremors. It is a rare issue among otherwise healthy people because the kidneys limit magnesium excreted in the urine.
Factors that develop a magnesium deficiency:
- alcohol use disorder
- Other medical conditions
- Certain medications
An individual with a magnesium deficit may experience the following symptoms:
- A loss of appetite
The person might experience additional symptoms if the condition becomes severe.
- Muscle contractions and cramps
- An irregular heartbeat
- Heart spasms
- Personality changes
Magnesium deficiency can affect other minerals, like calcium and potassium. Defects in these minerals can cause additional symptoms and complications.
A doctor may recommend magnesium supplements. Anyone who suspects they may have a nutritional deficiency should consult a doctor before taking a supplement.
3. Vitamin E deficiency
In 2011, doctors reported a male in his 20s who had a vitamin E deficiency and raised a tremor in his upper limbs and trunk. He also experienced:
- Modifications in gait and posture
- It isn’t easy to articulate
- a decline in cognition
Although the medical team determined that the tremor was caused by vitamin E deficiency (but noted that it is rare),
A high dose of oral vitamin E supplements is recommended to treat involuntary movements due to vitamin E deficiency.
Doctors can prescribe the correct dosage of supplements.
Researchers have managed to control muscle twitching using the drug gabapentin. Off-label usage refers to treating one condition by a doctor using a drug approved by the Food and Drug Administration (FDA).
5. Essential tremor
Essential tremor refers to the involuntary, repeated movement of a part of the body. It is a condition where the actions are repeated with constant frequency and force.
Essential tremor is the most common cause of tremors. Doctors don’t know why.
Essential tremor is a common symptom in people’s hands. Some people experience tremor in their hands that extends to their arms and heads. It can also affect the voice.
It doesn’t affect a person’s life expectancy. It can, however, affect the quality of life and lead to disability.
Essential tremors can be treated with both medical and non-medical interventions.
Doctors will try and find the best medication for each patient using trial and error. Below is a table that lists the three primary treatment options for essential tremors.
Although these drugs are not FDA-approved to treat essential tremors, some doctors may prescribe them off-label.
A person might find that weighing down their affected area helps to control their tremor. A weighted wristband may help relieve essential tremors.
For people with anxiety-related tremors, doctors might recommend relaxation techniques. Some doctors may recommend that you avoid caffeine as it can cause tremors.
There are four types of parathyroid glands. They are small and located in the neck. They produce parathyroid hormone, which raises calcium levels.
The term “hyperparathyroidism” refers to the overactivity of one or more parathyroid glands. Overactivity can cause a deficiency in calcium or potassium, which can lead to muscle twitching.
Hyperparathyroidism can also be manifested by:
- Muscle aches
- Muscle weakness
- Joint and bone pain
- digestive problems
- Memory and concentration problems
- kidney problems
Surgery to remove the parathyroid glands affected is the only cure for hyperparathyroidism.
Some drugs, like synthetic estrogen and bisphosphonates, can decrease calcium or parathyroid hormone levels and improve bone-related symptoms. They cannot treat hyperparathyroidism.
7. Tourette’s syndrome
Tourette’s syndrome, a neurological disorder, is characterized by repetitive and involuntary movements and vocalizations. These occurrences are called “tics” by doctors.
Tourette’s syndrome sufferers have multiple tics that begin in childhood. Motor tics, also known as movement tics, are frequent and sudden.
To be diagnosed with Tourette’s syndrome, one must have:
- Multiple motor tics may occur along with one or more vocal symptoms throughout the illness.
- Tics that last more than a year
- Symptoms that start before 18
- Unrelated symptoms to medications or other medical conditions
Doctors rarely treat Tourette’s syndrome. Children respond well to behavioral treatments for tics.
Tourette’s syndrome can lead to psychiatric disorders in children who need appropriate treatment. These could include:
- OCD, also known as obsessive-compulsive disorder or OCD.
- Anxiety disorder
- oppositional defiant disorder, or ODD
While tics may disappear over time, symptoms of any psychiatric disorder can persist.
8. Parkinson’s disease
Parkinson’s patients may feel tremors.
Other symptoms of Parkinson’s include:
- Instabile posture
- Walking is difficult
- Slow movements
Parkinson’s disease results in the loss of cells within a portion of the brain known as the substantia. This area produces dopamine, which is a neurochemical that controls and coordinates body movements.
Initial treatment for Parkinson’s disease was with levodopa. The body converts this synthetic form of amino acid into dopamine.
Supplemental levodopa can be used to control symptoms of dopamine insufficiency.
People may need to be treated with additional medications as the disease progresses. Doctors may prescribe these drugs in addition to levodopa.
- Catechol-O-methyltransferase inhibitors and monoamine oxidase inhibitors help slow the depletion of dopamine & enhance levodopa.
To further activate dopamine receptors, a doctor might also recommend pramipexole or ropinirole.
9. Amyotrophic lateral sclerosis
Lou Gehrig’s Disease, also known as ALS, is a progressive motor neuron disorder whose symptoms slowly worsen.
In its early stages, ALS may cause muscle twitches or weakness in the arm and hand. As the disease progresses, muscle weakness can develop, which can spread throughout the body.
As the disease progresses, breathing difficulties, such as speech and swallowing problems, can also occur.
ALS can be manifested in a variety of symptoms, including:
- Muscle Twitches
- Muscle Weakness
- Nasal speech, slurred
- Muscle Cramps
- Difficulty Swallowing Or Chewing
- Muscle tightness and stiffness
ALS is currently incurable. Some treatments can be used to manage symptoms and prevent complications. They also improve quality of life.
The FDA has approved these medications to treat ALS.
- Riluzole (or Riluzole): This drug reduces movement-related neuronal damage, but it cannot reverse it.
- Edaravone: This drug slows down a decline in day-to-day functioning.
When should you see a doctor?
Finger twitching in young, healthy adults is a sign of overexertion. It is caused by excessive use of smartphones, computers, and video games.
Consult a doctor if the twitching persists and there is no apparent cause. The doctor will most likely diagnose a neurological disorder.
Consult a doctor if finger tingling interferes with your daily activities and affects your quality of life. While some causes can be treated with vitamin supplements or rest, others may require medical intervention.
Although it is not a severe symptom, finger twitching could indicate a more serious medical condition. Do not attempt to diagnose yourself.
A proper diagnosis and early detection will help you get the best treatment for your symptoms.
A neurological disorder may be suspected by people who feel their fingers twitch. There are several causes for this condition that are relatively benign, such as overexertion, fatigue, and excessive caffeine intake.
A neurological condition can cause finger tingling. This person may also experience other symptoms.
If finger twitching persists or gets worse, consult your doctor.
