A member asked:

What does it mean when you have a vibration sensation under your skin on your upper thigh?

A doctor has provided 1 answer

Muscle Twitching: Muscle twitching is caused by minor muscle contractions in the area, or uncontrollable twitching of a muscle group that is served by a single motor nerve fiber. Muscle twitches are minor and often go unnoticed. Some are common and normal. Others are signs of a nervous disorder. See your doctor as there are many causes.
