Some think that they are simple muscle twitches caused by a lack of potassium or other vitamin or mineral vital to proper body functioning. This happens when the muscle is in a fatigued state, like during the days following a hard workout.
Or it could be a mild form of a Jacksonian seizure, itself a mild form of epilepsy. The part of your brain that controls muscle function is experiencing an electrical storm that causes different muscles to move involuntarily.
This sometimes happens in my upper arm or around my eyes. Usually a good sleep cures it.
