Causes of Finger Twitching

Twitching fingers occur lesser than benign muscle spasms, deficiencies in diet, or electrolyte inequality. Spontaneous twitching might also be a symptom of injury in the nerve or central nervous system disorder. Numbness or tickle sometimes goes along with the twitching. Affected individuals may seek a perfect diagnosis when the twitching increases in harshness, continues beyond the fingers, or is comes along with pain.

Nutritional shortcomings can alter electrolyte levels, which might lead to twitching fingers .Levels of Magnesium, calcium and Potassium  that are below normal often cause twitching or muscular  cramps. Diets low in calcium or high consumption of carbonated soda can add to abnormally low blood calcium levels and consequently muscle twitching or cramping.

Causes of finger twitching  

• Muscle Cramps – Small muscle contractions often result in muscular cramps in the finger which is a common causes of the twitching. This is normally not a cause for concern.
• Carpel Tunnel Syndrome – If we have carpel tunnel syndrome, then there is a nerve that is nicked in the wrist that passes through our carpel tunnel. This is mostly done to help relieve the pressure related to the median nerve. In doing so, it sometimes lead to twitching of the thumb or index finger.
• Nutritional Deficiencies – Certain nutritional deficiencies can result in an electrolyte inequality which can often leads to muscle spasms and cramps.
• Filament – A spontaneous twitching in the finger's muscle that is controlled by a filament or a single motor nerve fibre can often lead to finger twitching.
• Complex Regional Pain Syndrome –In this disease there is an intense pain or burning sensation in either the legs or arms or both. Uncontrollable quivering of the fingers is often a symptom.
• Multiple Sclerosis – This central nervous system disease has characteristic features of loss of muscular coordination and numbness. Finger twitching, in this case, is one of its easiest detected symptoms
• Parkinson's Disease – It is a genetic disease that originates either in our rib or shoulder area and then travels to the other body parts such as your fingers or thumbs.
• Side Effects – Certain drugs may cause twitching in our fingers as their side effects. These may or maynot revert back upon stopping the use of those drugs.
• Caffeine – It is said that too much caffeine or  sometimes withdrawals of caffeine can cause muscle twitching. This takes into account  coffee, soda and chocolate.
• Myopathy – This is a muscle disease that slowly leads to weak muscles. If our fingers are affected, twitching may occur.
• Exercise – If we exercise or overwork any of the muscles in our fingers, cramps can occur as well as muscular pain, spasms and fatigue.

Muscle twitching is thus caused by minor muscular contractions in the area, or involuntary twitching of a muscle group that is connected to a single motor nerve fibre. Muscle quivering is minor and often goes unobserved. Some are common and usual, but others are signs of a nervous system disorder.
