Top 12 Causes Of Finger Twitching
Fine movements in a tiny area of muscle in your fingers are called finger twitching. Common symptoms that are often present in addition to the twitching are numbness and tingling. When the twitching only occurs once in awhile, it is considered quite normal and it is usually just ignored. However, chronic finger twitching, even on a minor level, may be an indication of a serious nervous system disorder.
- Carpel Tunnel Syndrome – If you have carpel tunnel syndrome, there is a nerve that is nicked in your wrist that passes through your carpel tunnel. This is commonly done to help relieve pressure associated with the median nerve. In doing so, it often leads to twitching of the thumb or index finger. Carpel tunnel syndrome is common in people that perform repetitive movements with the hand or wrist either for their occupation or hobby such as a designer, painter, factory worker or golfer.
- Muscle Cramps – Small muscle contractions can result in muscle cramps in your finger which is one of the more common causes of the twitching. This is usually not a cause for concern.
- Nutritional Deficiencies – Certain nutritional deficiencies such as hypomagnesaemia, which is a magnesium deficiency or hypocalcemia which is a calcium deficiency can result in an electrolyte imbalance which often leads to muscle spasms and cramps.
- Filament – An uncontrolled twitching in your finger's muscle that is controlled by a filament or a single motor nerve fiber can often result in finger twitching.
- Amyotrophic Lateral Sclerosis – Progressive degeneration of your motor neurons occurs in this motor neuron disease. Twitching in your finger or thumb are believed to be possible causes.
- Multiple Sclerosis – This familiar central nervous system disease offers characteristic features of loss of muscle coordination and numbness. Finger twitching is often one of its easiest detected symptoms. Multiple sclerosis affects 1 in 100,000 adults over the age of 50. If you have chronic twitching in one or more of your fingers, you must get tested for this disease.
- Parkinson's Disease – This genetic disease originates either in your rib or shoulder area and will then travel to other body parts such as your fingers or thumbs.
- Side Effects – Certain drugs such as diuretics, corticosteroids and estrogen are often causes of twitching in your fingers.
- Caffeine – It is reported that too much caffeine or withdrawals of caffeine can cause muscle twitching. This includes coffee, soda and chocolate.
- Myopathy – This is a muscular disease that slowly weakens the muscles. If your fingers are affected, twitching will often occur.
- Exercise – If you exercise or overwork any of the muscles in your fingers, cramps can often occur as well as muscle pain, spasms and fatigue.
There are not any home treatments for finger twitching. If it is just a random occurrence, it is probably nothing to be concerned about however, if it is a common occurrence, you should not ignore it. Frequent twitching should actually be taken quite seriously because it may be a sign of some type of nervous system disorder. It is important that the underlying cause is determined and treated.
A neurologist will be able to conduct appropriate tests for evaluation. A nerve conduction test is the most common test performed accompanied by a urine test and MRI to check the spinal cord or look for a brain tumor. Tests will often also include fasting to test for deficiencies in vitamins and minerals.
