I've been having extreme burning, pins and needles down both my legs and glueteus maximus. I also have weakness in both my leg muscles. I get involuntary muscle twitches in my thighs and my calves. I had an MRI which came back negative for pinched nerves. My doctor didn't like my muscle reflexes, when the muscle was supposed to stop, it kept jerking, this is why the MRI was done, however they didn't find anything? This has been going on for 3 years now, and since the first year has progressivley gotten worse. This started after an accident. Is there anyone out there that has had these problems, might shed some light. I'm only 22!, and walking is an effort. I also wake up at night because it feels like my lower body is being shocked!
