Thanks for addressing my problem. I am 32 and for the first time, I am having arm problems. I throw a fastball ( cut and 4 seamer, max at 85), curveball, splitter and change up.I had a several year lay off, before returning to play (I played last year and this year). I am very active, in terms of running and weights. My arm does not hurt when I play long toss or when I warm up. Normally, it hurts after I through about 30 pitches or so from the mound. I have no problems with my shoulder, just bicep tightness that hurts badly enough that I cannot throw more than 1 inning and usually the pain lingers on for a day or 2 after I throw. I have tried to make sure that I am not gripping the baseball too tightly and that I have a sufficient enough warm up. I play short stop when I don’t pitch relief. I am wondering if playing infield could be causing some problems or could it
be as simple as curveball mechanics. When my arm starts hurting I don’t lose any velocity, the pain just becomes too much to handle. Also, could it be that it is some shoulder pain that is simply referring to my bicep?
Thanks for your help,
