So, I was doing some heavy str8 bar bicep curls yesterday afternoon. After the 2nd set, I notice severe pain in the shoulder. It feels like it's directly in the articular area of the head of the humerus and scapula. It's so effin painful that I can't even raise my arm to moar than about a 45 degree angle. It even kept me awake for several hours last nite because I couldn't get into a comfy position. I've dropped a lot of cash recently on AAS and I'm hoping this isn't gonna keep me from training moar than a coupla days. Anyone ever had this experience b4? How long should I expect to be out of the gym? Thx & GYCH!
