why does my right thumb keep twitching

The reason a twitching thumb can really cause worry is because the thumb is a very small part of the body a digit and when muscles of a digit (be it a thumb, index finger or toe) twitch, the digit typically jumps. It is the jumping that often worries a person when the thumb twitches, but whether or not a finger jumps or visibly moves, upon twitching, has absolutely nothing to do with the likelihood that there s a fatal disease process going on. The thumb contains voluntary muscles. So why wouldn t it occasionally twitch? Just like other muscles twitch (upper legs, back, arms, calves, etc. ), the thumb is not exempt to this very common, benign phenomenon. The worry factor kicks in because when a thumb twitches, it can be seen in action.

Once the weakness is present, it will always be present and will only get worse. This is in contradistinction to the weakness and off days that may be experienced by athletes and normal, active people. A fairly typical scenario for an individual with ALS is this: The person is fit and active, and begins to develop an isolated symptom of weakness such as unilateral foot drop. The weakness is subtle at first. The person attributes this to a bad knee or some type of orthopaedic problem. Over time, not only does this problem not remit, but other signs of weakness develop in other parts of the body. This is an insidious process, and most people do not initially come to a neurologist for these signs and symptoms. , such as Isaac syndrome.

Drug overdose (caffeine, amphetamines, or other stimulants). Lack of sleep. Drug side effect (such as from diuretics, corticosteroids, or estrogens). Exercise (twitching is seen after exercise).
