Over the past few days or so I've noticed a strange pulsating feeling in my right thigh (right of center about 6 inches above knee).  It isn't painful, but it is strange in that there is no regular rhythm to it.  There is also a mild numbing sensation like my thy is waking up from being asleep but never quite does. It comes and goes throughout the day, sometimes it's pretty active other times not.  I would describe it almost like a jello type substance is being squeezed through my thigh.  Also, I don't think it's a muscle twitch, since it feels very deep and I don't see my leg moving.
