So ever since I started working out whenever I do military or push presses, (I do not perform Military anymore I like my shoulders and watched my buddy seriously injure himself doing it) I get a clicking feeling in my entire arm kind of like somebody plucking a guitar string that run through my arm from my hand almost to my shoulder. Today by the third rep of my first set it started to feel like someone was heating that guitar string to the point where it felt like my arm was on fire, It was like shooting pain it was as if someone was actually heating a thin strand inside my arm. I finished the set and went on with my workout but my left arm was more or less useless from that point. Overall a crap workout. I assume its something with my nerve any ideas on how to avoid this? Its happened forever but this is the first time pain was associated and it was definitely a lot of pain.
