?fasiculations: Tough to say what you are experiencing over the computer, but it sounds like it may be a muscle fasiculation, which can be a normal and benign condition that occurs with minor electrolyte imbalances or muscle strains and nerve irritation. These are usually self limiting and go away in time or even with massaging the area, etc. If they continue, see the Dr. Best wishes.
