Hi, kevin25. Even though the growth plate isn't cracked or broken, if it is "aggravated" then that can linger for a long time. 2B aggravated his growth plate right before he turned 12, and he had pain and periods of time where he had to shut down the arm on and off for the next two years. It happened enough times, and the pain was specific enough, that the doc and the PT finally said, "you don't need to come back - you know what to do." It was frustrating, but he kept hitting and fielding and kept improving even though he couldn't throw. And the coaches moved him from SS/3B/P to 2B, which helped save his arm during the times where he was healthy. We took care of it and listened to the pain. Now that he's 15, he's 100% and moving back to the left side of the infield and pitching again. The key is to listen to the pain, and believe him if he says it hurts, and understand that the world won't come to an end if he can't throw for a while. Sometimes it felt like it was the end of the world, but what do you know - we're still here.
