I've had 4 emg's and they have come back normal except the last one showed lots of twitching which I didn't notice. My question is I'm experiencing more pain in my shoulders especially my left and a pressure/pain in my spine. I still experience pain down the top of arms and is getting worse. My body has this hot/tingling feeling and my bones in my shoulders pop all the time. Besides that I have this on going head/neck pain. I don't know what's going on. Any thoughts.
