Thumb and index finger tremor: 9 causes and when to see a doctor
9 causes and when to see a doctor
A twitch is a small, involuntary contraction and relaxation of a muscle or group of muscles. Medication side effects, physical exertion, fatigue, and excessive caffeine can all cause twitching in the fingers.
People with finger twitching may worry that they are developing a neurological disorder. However, when this twitching does not accompany other symptoms, it is typically not a cause for concern.
In this article, we explore nine causes of finger twitching and their treatments. We also offer advice about when to see a doctor.
Share on PinterestFinger twitching is a side effect of some medications.
Muscle spasms and twitching can be side effects of some medications, including:
- corticosteroids
- isoniazid, an antibiotic
- succinylcholine, a muscle relaxant
- flunarizine, a drug that interrupts the movement of calcium
- topiramate, a drug that helps treat epilepsy
- lithium, a psychiatric medication
If a person thinks that a medication is causing muscle twitching, they should speak with their doctor before stopping the treatment.
The doctor may recommend lowering the dosage or switching to an alternative medication, if possible.
A magnesium deficiency can cause muscle cramps and tremors. This issue is rare among otherwise healthy people because the kidneys limit the amount of magnesium excreted in urine.
However, certain factors can increase the chances of developing a magnesium deficiency. These include:
- alcohol use disorder
- some other medical conditions
- certain medications
A person with a magnesium deficiency may initially experience:
- a loss of appetite
- nausea
- vomiting
- fatigue
- weakness
If the deficiency becomes severe, the person may experience additional symptoms, such as:
- numbness
- tingling
- muscle contractions and cramps
- an irregular heartbeat
- coronary spasms
- personality changes
- seizures
A magnesium deficiency may affect other minerals in the body, such as calcium and potassium.
Deficiencies in these minerals can cause additional symptoms and complications.
Treatment
A doctor may recommend magnesium supplements. However, anyone who suspects that they have a nutrient deficiency should speak to a doctor before trying a supplement.
In 2011, doctors reported a case of a male in his mid-20s who had a vitamin E deficiency and developed a tremor in his upper limbs and trunk. The man also experienced:
- changes in gait and posture
- difficulty articulating
- a decline in cognition
The medical team concluded that the tremor resulted from the vitamin E deficiency, but noted that this symptom of the deficiency is rare.
Treatment
The treatment for involuntary movements caused by a vitamin E deficiency is a high dosage of oral vitamin E supplements.
Anyone who suspects that they have a nutrient deficiency should consult a doctor, who can recommend the right dosage of supplements.
People with benign fasciculation syndrome (BFS) have widespread involuntary muscle twitches.
Symptoms are usually present for years, and some clinicians only diagnose BFS if the symptoms have existed for at least 5 years.
Doctors do not know what causes BFS. However, one 2013 study found a link between this syndrome and decreased neurological activity in the small nerve fibers in the skin and sweat glands. Confirming this relationship will require more research.
Treatment
BFS does not progress to motor neuron disease and does not require treatment.
Nonetheless, researchers have successfully controlled muscle twitching with the drug gabapentin, which acts on the nervous system.
Also, some doctors have found that certain drugs that treat epilepsy, such as carbamazepine and phenytoin, can reduce muscle twitches.
It is worth noting, however, that using the drugs above to treat twitching constitutes off-label use. “Off-label use” refers to a doctor treating one condition with a drug that the Food and Drug Administration (FDA) have approved to treat a different condition.
Essential tremor is the repeated, involuntary movement of a body part. In a person with essential tremor, the movements occur with consistent frequency and force.
Essential tremor is the most common neurological cause of tremors, but doctors do not know what causes the condition.
People usually experience essential tremor in their hands. In some people, the tremor extends to the arms or head, and it can also affect a person’s voice.
Essential tremor does not change a person’s life expectancy. However, it can affect a person’s quality of life and cause disability.
Treatment
Some people seek treatment for essential tremor, and both medical and nonmedical interventions can help.
Regarding medication, doctors will use trial and error to find the most appropriate drug and dosage for each person. The following table lists the first, second, and third lines of treatment for essential tremor.
| First line of treatment | Second line of treatment | Third line of treatment |
| propranolol | gabapentin | nimodipine |
| primidone | pregabalin | clozapine |
| combination of propranolol and primidone | topiramate | |
| clonazepam, alprazolam | ||
| atenolol, metoprolol | ||
| zonisamide |
These drugs have not received FDA approval to treat essential tremor specifically, but some doctors prescribe them for this purpose on an off-label basis.
Also, a person may find that weighing down the affected area helps control their tremor. For example, a weighted wrist band may help with essential tremor in the hand.
Additionally, doctors may recommend relaxation techniques for people whose tremors are worsened by anxiety. They may also recommend avoiding caffeine, as this can increase tremors.
There are four parathyroid glands. They are small, they sit inside the neck, and they produce parathyroid hormone, which helps raise levels of calcium in the blood.
The term “hyperparathyroidism” refers to overactivity of one or more parathyroid glands. This overactivity causes an imbalance in calcium and potassium in the body, which may lead to muscle twitching.
Other symptoms of hyperparathyroidism include:
- muscle aches
- muscle weakness
- joint and bone pain
- digestive problems
- fatigue
- depression
- irritability
- problems with memory and concentration
- kidney problems
Treatment
The only known cure for hyperparathyroidism is surgery to remove the affected parathyroid glands.
Certain drugs, such as bisphosphonates and synthetic estrogen, may decrease calcium or parathyroid hormone levels and improve bone-related symptoms. However, they cannot cure hyperparathyroidism.
Tourette’s syndrome is a neurological disorder characterized by involuntary and repetitive movements and vocalizations. Doctors refer to these occurrences as “tics.”
People with Tourette’s syndrome have multiple tics that start during childhood. Movement, or motor, tics are sudden and recurrent. They are usually triggered by an urge and can affect any part of the body.
In order to receive a diagnosis of Tourette’s syndrome, a person must experience:
- multiple motor tics and one or more vocal tics throughout the illness, though these may not occur together
- tics that persist for more than 1 year
- symptoms that begin before the age of 18
- symptoms that are unrelated to substances or other medical conditions
Treatment
Doctors usually do not prescribe medication to treat Tourette’s syndrome.
However, children tend to respond well to behavioral interventions for tics.
Children with Tourette’s syndrome may have accompanying psychiatric disorders that require appropriate treatment. These may include:
- attention deficit hyperactivity disorder, or ADHD
- obsessive-compulsive disorder, or OCD
- anxiety disorder
- oppositional defiant disorder, or ODD
Over time, tics can disappear, but symptoms of any psychiatric disorder may persist.
Parkinson’s disease is a disorder of the brain that usually occurs in adults over 50.
A person with Parkinson’s may experience a tremor. This typically begins on one side of the body and worsens over time.
Some other symptoms of Parkinson’s disease include:
- unstable posture
- difficulty walking
- slow movements
Parkinson’s disease causes a loss of cells in a part of the brain called the substantia nigra. This area makes dopamine, a neurochemical that helps control and coordinate body movements.
Treatment
Doctors initially treat Parkinson’s disease with the drug levodopa. This is a synthetic version of an amino acid that the body converts into dopamine.
Taking supplementary levodopa helps control some symptoms of dopamine deficiency.
As the disease progresses, people need additional treatments. Doctors may prescribe the following drugs in addition to levodopa:
- Catechol-O-methyltransferase inhibitors and monoamine oxidase inhibitors: These help slow the depletion of dopamine and increase the availability of levodopa.
- Drugs that act on acetylcholine receptors: These help reduce muscle twitching and rigidity.
A doctor may also prescribe ropinirole or pramipexole to further activate dopamine receptors in the brain.
ALS, or Lou Gehrig’s disease, is a progressive motor neuron disease, and its symptoms gradually worsen over time.
In the beginning stages, ALS can cause muscle twitches in the hand or arm.
Over time, a person may develop muscle weakness, which can spread to other parts of the body.
Swallowing, speech, and breathing problems can occur as the disease continues to progress.
Some common symptoms of ALS include:
- muscle twitches
- muscle cramps
- muscle tightness and stiffness
- muscle weakness
- slurred, nasal speech
- difficulty chewing or swallowing
Treatment
Currently, there is no cure for ALS. However, certain treatments can help control symptoms, prevent complications, and improve the quality of life.
The FDA have, so far, approved the following medications to treat ALS:
- Riluzole: This drug reduces damage to neurons involved in movement, although it cannot reverse the damage.
- Edaravone: This drug slows a decline in daily functioning.
In young, healthy people, finger twitching is likely a symptom of overexertion. Often, this stems from overuse of cellphones, computers, and video games.
If the twitching continues, with no clear cause, consult a doctor. They will likely perform an examination to rule out a neurological disorder.
If finger twitching affects daily activities or the quality of life, see a doctor. Some causes can be treated with rest or vitamin supplements, while others require further medical intervention.
People who experience finger twitching may worry that they have a neurological disorder. However, there are many relatively harmless causes of this issue, including overexertion, fatigue, and consuming too much caffeine.
If finger twitching results from a neurological diseases, the person will usually experience additional signs and symptoms.
See a doctor if there is no clear cause of finger twitching or if the movements persist or worsen.

Periodically appearing trembling affecting the fingers or eyelids, doctors habitually call tremor, subdividing this symptom into two subspecies according to its origin: physiological and pathological. The first one occurs at least once in the life of every person, it can be caused by sudden excitement, severe stress, muscle strain; the second one is evidence of various pathologies and serious disorders inside the human body, a qualified doctor will help to establish them.
Register with a specialist through the website
As a rule, if you experience trembling of the fingers, eyelids, it is recommended to visit a neurologist, since most of the underlying causes are within his competence, but in about a third of cases this specialist can redirect you to a narrower doctor – an endocrinologist.
If, due to such symptoms, you were prescribed to visit an endocrinologist, it is most convenient to do this at the Practical Medicine Medical Center in Yuzhnoye Butovo, where one of the leading endocrinologists of the capital sees you.
Causes of tremor
In order to prescribe a competent, balanced treatment of tremor, at the first stage of diagnosis, it is necessary to determine the cause of such an organism’s reaction with the maximum degree of probability. Among the most common:
- Hypothermia in winter.
- Strong irritating emotional factors – stress, anger, excitement, fear.
- Entry into the body of poisons, toxins of various origins (poisoning) – alcohol, drugs or chemicals.
- Painful narcotic hangover, in the common people called brittle.
- Hypoglycemic coma occurring in diabetic patients.
- Violation of the normal functioning of the thyroid gland.
- Strong physical or psycho-emotional overstrain.
- Parkinson’s disease.
- Hereditary ailments, including essential tremor, accompanied by spontaneous trembling of the muscles at rest.
- Possible brain injuries and pathological diseases – malignant and benign tumors, abscesses, etc.
- Changes in the hormonal background in children when they are in adolescence, accompanied, for example, by exams, their consequence is an increased nervous load.
Observing one or more of these factors in yourself, do not rush to engage in self-diagnosis and, moreover, self-treatment. Only a doctor can make an accurate diagnosis, which you should visit as soon as possible!
Diagnosis and treatment
During the initial examination, the first thing the doctor will do is to observe the nature and amplitude of muscle contractions: where they occur initially, whether they are symmetrical, what other deviations are accompanied. The nature of the movements, their intensity and type (left-right, up-down, sweeping, chaotic, etc.
) will allow the doctor to identify the root causes, prescribe additional tests, examinations, and refer to a more specialized specialist.
Treatment varies from case to case, but there are a number of principles that are common to all manifestations of tremor:
- Emotional stabilization – try to remain calm.
- Do breathing exercises – it calms, plus relaxes the muscles.
- To restore the psycho-emotional background, relaxing baths with essential oils, taking herbal teas, decoctions will help.
- Do what you have long dreamed of – sports (preferably yoga or swimming), learn to embroider, sculpt, knit – this way you will be able to reduce spontaneous trembling of hands and eyelids.
- Eliminate foods containing caffeine, including tea, if you smoke or drink, stop immediately.
These, including a number of other tips, will certainly be given to you by our endocrinologist – Taller Nikita Aleksandrovich, he perfectly knows the intricacies of the work of the endocrine system of the body, not only from a theoretical point of view, but also from a practical one.
The doctor conducts a stationary reception within the walls of the clinic.
To get an appointment with him is a great success, because, knowing about the professional qualities of a doctor, many people strive to do this. Patients of “Practical Medicine” have more chances, do not miss them, and then no trembling, even temporary, will be terrible!

What is Parkinson’s disease? Part 2
Parkinson’s disease is the most common cause of parkinsonism syndrome, accounting for up to 80% of its cases. At the age of over 75, at least 2% of people suffer from it.
Parkinson’s disease most often manifests itself after the age of 50, but cases of the onset of the disease are not uncommon at an earlier age. Men get sick slightly more often than women.
How does Parkinson’s disease manifest itself clinically?
In Parkinson’s disease, there are motor (“motor”) and “non-motor” disorders.
What are “motor” disorders?
Symptoms of the disease develop gradually. Trembling, stiffness or awkwardness in one of the limbs usually appear first, less often the disease initially manifests itself as a change in gait or general stiffness.
At the onset of the disease, attention is often drawn to pain and tension in the muscles of the limbs or back (one of the frequent misdiagnosis in patients with initial manifestations of Parkinson’s disease is humeroscapular periarthritis)
Initially, symptoms occur only on one side of the body, but gradually become bilateral over time.
Movements become more and more slowed down, facial expressions are weakened. Because of the rare blinking, the look seems piercing, prickly.
Friendly movements disappear (for example, hand movements when walking).
Fine finger movements are difficult (for example, when fastening buttons, threading a needle). Handwriting becomes smaller and less legible.
It is increasingly difficult for the patient to change position, for example, to get up from a chair or turn in bed from side to side.
The gait changes: the steps become shorter, shuffling. On the affected side, the patient is forced to drag his leg.
Due to the predominance of the tone of the flexor muscles, the head and torso of the patients lean forward, the arms are bent at the elbows and pressed against the body, the legs are bent at the knees (“the petitioner’s position”).
Speech becomes muffled and monotonous.
Trembling (tremor) usually occurs at rest, for example, in a hand lying quietly on a knee, or a leg when the patient is sitting and not leaning on it.
The movements of the thumb and forefinger are reminiscent of “rolling pills” or “counting coins.”
In addition to the extremities, trembling often involves the lower jaw and lips, but rarely the entire head.
Trembling depends both on the emotional state of the patient and on his movements. For example, a tremor in the arm decreases or disappears during its movement, but increases with the movements of the other arm or legs (including walking).
The condition may fluctuate during the day or from day to day, depending on psycho-emotional, and possibly weather factors. Feelings of anxiety, trembling, stiffness can be intensified when you are in an unfamiliar environment, surrounded by strangers. And vice versa, when you stay with your family, among good friends, if you have the opportunity to do what you love, physical activity is greatly facilitated.
According to the famous literary critic and master of fiction I. L. Andronnikov, known for his oral stories and also suffering from Parkinson’s disease, his symptoms suddenly decreased as soon as he went on stage.
