I was wrestling yesterday at my club team practice and went for a headlock against a much bigger guy. Arm hit, guy didn't budge, but my body kept rotating. Felt two series of pops: first one as I was rotating, second as I turned back to bail out after onset of pain. It's a day later and I'm starting to worry I may have torn my biceps. Pain/weakness is localized where the chest meets the shoulder, shoulder, and down the first third of bicep. Having significant trouble doing any motion that requires chest to flex or rotating my forearm outward. Also just noticed bruising along the first third of the bicep. No tell-tale balled up bicep deformity, though. Has anyone here had a similar injury experience? Does this need to get checked out?
