During my days of mountain bike racing, I dislocated my shoulder and separated the A-C during a bad spill. Through professional help, physical therapy, and time, I recovered. I am now nearing 50 and suffer no difficulty or weakness from this injury. My shoulder is as strong as ever and is probably stronger than most half my age. I can shoot heavy bows using the Hill style, I can throw breaking balls, I have a full range of movement, and I suffer no pain beyond normal muscle soreness. I credit this to seeking and following the best professional advice available to me at the time. I'd suggest the same for you.
