I'm on the wrong side of 50. Had rotator cuff surgery in 92. Never was 100% after that. I've had pain in both shoulders on/off for years. As well as elbows, wrists, hips, knee, .... u get the point. What I have learned is if I want to still play hard -- and I do -- rest and ice and stretching are the key. Rest is the most important thing and the hardest to employ. Missing a week or 3 or 8 seems like forever - at the time. In the scheme of years, though, it's nothing. I have mostly been too hard-headed to accept that, but have gotten better the last couple years. Of course, go see an ortho and get a diagnosis. But if it comes back negative, you know the answer.
