> 100 causes: This could be due to no less than a hundred different possible causes (no kidding). While there may be no ascertainable explanation, a complete history and physical examination will help to narrow and define the possible causes which include denervation atrophy, excessive use, central nervous system disorders, etc.

Check it out: I'm assuming you're describing muscle movement in your bicep, tricep, or deltoid. Is there any weakness associated with it? If it persists, you should definitely go to your family md for an evaluation. It could be muscle fatigue but if it persists, it needs evaluation.
