What is considered normal soreness for a high school pitcher? My 2012 son is throwing mid to upper 80's and has minor soreness in the back shoulder after a start that lasts for a few days later.
He becomes a bit testy when I ask him about it and he is pitching well and not showing any signs of discomfort on the mound. The soreness the day after pitching is not new but since he has started hitting 88-89, the soreness lingers several days later. I am thinking it may be a sign the decelerator muscles in the back of the shoulder may be a bit weak but I would appreciate any advice.
