So about two weeks ago i started having muscle twitches, they started in my thigh but spread to my calves, arms, neck, and every once in a while the face. I'm 6'4, 210 pounds, and i used to have high blood pressure, though i never took anything for it, i'm almost certain its down to normal now though. Last night i laid down and after a while my legs felt like they had bad sunburn, and i couldn't sleep, it was terrible really. Woke up two hours later for school and still had minor burning in left calf and now that spread to my face and knees. It's not really a bad feeling, just something concerning, I'm not weak or anything, i jog and play volleyball regularly and i don't even feel weak now! Is this something to worry about? i'm going to a doctor in about three hours.
