My son is 4 months post. His first few weeks were difficult, not for any other reason than he was instructed NOT to move his shoulder any more than absolutely possible. It was a pain to have to bath and take care of school work when he wasn’t allowed to move his shoulder and his arm was locked into place with a special shoulder sling. Tell mom to buy some of that Press and Seal plastic wrap. It works great for placing on your shoulder so you can take a shower and keep the shoulder dry.
My son has been going to PT for a little over a month; he was initially doing some special stretches for a month prior to that. He had a Dr visit Wed and we asked the doctor why he could do all of the PT and stretches and he felt no pain or discomfort at all. He said, 30 more days and he could start to soft toss. I understand that throwing is when the “discomfort” starts.
As for recuiting: my son missed his senior year, so we had to find a school that was willing to take a chance on a barly know pitcher.
