I have a bad elbow and shoulder, both left arm. When I am doing bench, some times the pain is very strong. I tried to rest, used some Voltaren pills, took magnesium, vit. C E, etc. Doctors say that everithing is fine! As this wasn't enough, I have some pain on the heart area and I cannot distinguish if it is muscle pain or something vascular, it hurts alot when I breed intensivly after heavy bench or heavy squat! What do you guys think?
