I havehad feeling of vibrations in myleft leg feels like my cell phone vibrating on me but not. like a deep muscle tremor really fast. no pain what 2do?

Vibration: I had the same sensations before cell phones era, perhaps triggered by the on call pager when i was an intern. The mechanism is not well understood but it is very common and appears to be a benign process. Myokymia, myotonic discharges or sensory memory processing may be explanation. If in doubt check with your physician to make sure there is no other problem that may suggest a medical condition.
