Tremor is an uncontrolled, rhythmic, muscle movement involving to-and-fro movements of one or more parts of the body. It is the most common of all involuntary movements and can affect the hands, arms, head, face, vocal cords, trunk, and legs. Most tremors occur in the hands. In some people, tremor is a symptom of another neurological disorder. The most common form of tremor (essential tremor), however, occurs in otherwise healthy people. Although tremor is not life-threatening, it can be embarrassing to some people and make it harder to perform daily tasks.
Multiple treatment options are available, once again a proper diagnosis is the key to the right choice.
