I have a shoulder owieeeee

I guess with aging comes aging problems, my left shoulder has a rotator problem due to decreased encapsulation.  For now the Dr. prescribed an anti-inflammatory and exercises to strengthen the area.  I'll see him in six weeks to see what's next if it is still pretty sore.  I can swim front crawl and that's it, which is fine.  I don't need the other strokes for triathlon..right :))
