KT, don't take this lightly. Speaking from experience - I fell on a trail run when I was 40. Shoulder hurt like hell for months but I was used to it as I have genetically poor shoulder design (wide with no support). I blew it off and dealt with the pain. Fast forward 7 years and the Ortho doc says "looks like you broke your shoulder a while ago". No hope for me other than a man-made replacement which basically means the gym is off limits. Hell with that...man created ibuprofen for a reason.
