Yes, I'm 27 and for the past year or two I've been going down hill. Chest pains, back pain, etc. I've even dislocated my shoulder twice within the past year. I found that I can no longer throw or punch with my right arm (good arm) without dislocating it. And man is that shit painful, I have yet to experience anything worse than that.

And if I stretch my legs too hard, instant charlie horse. h: It sucks to wake up at 3 in the morning with that pain.
