I've been working out for a while and recently my left bicep has been acting up. First of all it started to feel weaker during bicep curls and my arm would seem like it wasnt getting enough blood in it after workouts if i didnt keep my arm vertical because it got "tingly". So I took a week and a half off and then came back to working out. Anyways it seems to have gotten better but still feels kind of odd during workouts. the veins seem to pop out like mad on my left forearm, like something out of a sylvester stalone movie. Anyways any suggestions as to what I should do? I'm probably going to go see a doc avout this sometime soon but I thought I'd ask here first.
