Twitching and trembling

If any part of your body begins to move involuntarily or without your control, consult this PDF. Such movements can include twitching, trembling, or shaking, for instance, of the hands, arms, or head. Most of the time, these motions are simply the product of fatigue, stress, or a hereditary propensity and shouldn’t be cause for concern. On rare occasions, though, the symptoms may be brought on by a condition that needs to be treated by a doctor, like excessive alcohol use or a neurological illness. Always inform your doctor right away if you have any involuntary movements coupled with weakening in the body area that is being affected. There may be a need for diagnostic tests.
