About 4 wks ago I started itching all over my body, but no rash no hives.  My PCP gave me some meds, made me drowsy so I stomped taking them after two days.  After about two weeks the itching subsided and finally stopped.  After the itching stopped and few days (3-4) my legs started to twitch while I was asleep to two nights straight.  Didn't think much of it until day 3 my thighs were achy and there was a sore spot on my right thigh, but no brusing.  My legs ached and twitched while I rested.  The pain started to move up my right side toward my back, I immediately rested.  Today, my legs (calf) and thight are still twitching, even while I type.  My left (tricept) arm aches and is somewhat tingley and my pinky & ring finger are tingley and numb.  I've had this particular thing happen before, but my PCP said is was probably a damaged nerve.  I know the difference in aches and muscle soreness.  My aches occur when I' resting, sitting or lying down.  No blurred vision.  Just got blook work results from PCP and everything in normal.  I ususally walk for 30 min a day, but today I was EXTREMELY tired.  Sporaticly, my limbs (legs and arms) will jerk.  Sometimes jerk so hard they wake me up if I'm asleep.  Sometimes I have a sharp shooting pain in my head that starts from the back of my right ear to the back of my head.  Sometimes the pain will be behind my right eye.  Should I be concerned?  I don't smoke, drink and I rarely eat red meat.  I've been loosing weight (intentionally) to get my cholesterol down.  Does anyone have any tips?
