Nagging issues with my right shoulder for probably the past 3-4 years. Couldn't ride my bike at all last year, and had no throwing power whatsoever, which as an outfielder, it relatively important. Finally opted for surgery in September of 2013. When baseball season started, it was feeling pretty good. I gunned a ball from dead center field and almost fainted it hurt so bad. Needless to say, the surgery apparently didn't work.
I can at least ride my bike again, which is nice. It definitely sucks knowing that my arm might never be able to hold up to throwing hard again though. I played the entire season regardless.
