I have this pain in my left shoulder when i bench. The more decline, the more it hurts. I had this last year around the same time and it went away on its own when i took a week off. I took two off and it still hurts. I take joint support and fish oil on a daily basis and it helps my knees and elbows so i know its working, but doesnt do much for my shoulder. I have strict form on every lift i do with a slow negative and a moderate positive (not slow but not fast.) I do however always try to get full range of motion, so i stretch the muscle as much as possible every rep. When i bench i uually go a little more towards the neck, but not completely a neck press; usually about clavical level. Just to get a little more of a stretch.
Its just lateral of the clavical; front side. Starts there and goes down just a little bit. half inch to an inch maybe. It doesnt cause me to bench any less, its more just annoying. But i dont want to further injure it. Any idea whats wrong or how to fix it? Thanks.
