<s>[INST] My son was in wrestling practice and someone pulled his shoulder forward. The coach moved his shoulder around and said there was nothing wrong with it, but he cannot lift his arm in front of him or up from his side. He can lift it behind him slightly better but not all the way. I have given him ibuprofen and put ice on it for 20 minutes but it did not seem to help. What should I do? [/INST] Hello, i have studied your case and I think that your son may be having shoulder cuff tear. It can be diagnosed with the help of MRI. If there is partial tear then it can be recovered with rest and physiotherapy. If there is complete cuff tear then he might need surgery for this. In both cases an MRI is must. I hope this answer will be useful for you. Let me know if there is any other followup questions. Thanks </s>
