Yesterday we started our pitching practice and went through normal warm up process. She takes a light jog, throws overhand, fields some grounders. Once she has a little sweat going, we start with the pitching. First drill we typically do is arm whips from the 9 o'clock position. On her very first pitch, she felt something wrong in her shoulder area. We immediately shut down. Since she is 12 yoa, it is hard to get her to explain exactly what she is feeling. We iced her down and as the night went on, she started feeling better. Her description is that its muscular. Sounds like a possible muscle strain in the front of the shoulder. Obviously if it is still sore after a couple days, she will get it examined. This is the first time she has ever had to shut down a practice or game for an injury. Has anyone else had experience with this type of injury in such a young girl? Shoulder injuries are something that could really derail her pitching plans. We really stress proper mechanics to prevent damage. The fact she got injured and her arm was basically at her side gives me some hope it is only a muscle spasm or pull verses structural. Kind of waiting on pins and needles.
