DD is 10yrs old. We were at a tryout and DD was pitching for the coach. She was throwing hard and it was the fastest Ive seen her throw. After a couple pitches she said her shoulder hurts and we stopped. Her arm had no pain when at rest. So I gave her a couple days rest and we tried to do some light overhand throwing and instantly she had pain so we stopped. I took her to the doctor next day. Doctor says shoulder strain and says no throwing for 2 weeks and to start lifting weights and bands to strengthen shoulders. I've found some shoulder exercises online and that what were doing. If anybody has advice or thoughts please feel free to share
