Hi, my daughter is 14 and had been diagnosed with spondylitis. Rested her for 6 weeks doing core exercises, tried to come back pitching and pain still there. Has been resting for 4 weeks now, aggressive core training now... Threw at half speed last night, felt okay, ramped up to 3/4 speed, pain is back. Seems to be painful right before she lands her front foot. HS try outs in 1 month, feeling aggravated, worried, this girl has worked so hard, for 5 years , never having any problems of any kind, I'm also down right mad, because in Feb. I found out coach had her pitching on concrete floor. Daughter being the incoming freshman wanted to show the coach how hard she could throw, and that's when the pain started. My daughter is 5'4", 106 lbs. and throws in upper 50's. there is so much potential here. Just wanted to talk to someone who has gone through this,no one in this area has heard of this.
