My son is a 14 year lefty pitcher. He was going through a growth spur with knee pain. Continued to play through the pain and pitched. Started to complain about back pain and was shut down for 2 weeks. Got back up and threw for about 30 minutes more pain. Shut down completely. MRI revealed a possible pars fracture. Is this growth spur injury and will he have future problems from this. The Dr suggested 6 to 12 weeks down but no brace. I live in Tampa and may want to have a second opinion if you know any doctors in my area. He is currently seeing Dr Cronen. He will be shut down for 13 weeks and then PT to strengthen core muscles. Just trying to see what to expect.
