<s>[INST] I have a shoulder impingement and my upper arm is sore. i ve been having physical therapy and it s improving Just now I was massaging it pretty hard and all of a sudden became unable to fully move my hand. I can t bend it back at the wrist and bend back my fingers at the same time. Did i damage a nerve? have a stroke? otherwise I feel totally fine. [/INST] Hello, I have studied your case. Due to compression of nerve root there can be pain.Also, there can be large disc bulge which is compressing over spinal cord. For these symptoms analgesic and neurotrophic medication can be started. Till time, avoid lifting weights. You can consult physiotherapist for help. Physiotherapy like ultrasound and inferential therapy will give you relief. I will advise checking your it B12 and it D3 level. I will advise you MRI spine. If nerve compression becomes symptomatically severe then surgical decompression will give permanent relief. Hope this answers your query. If you have additional questions or follow-up queries then please do not hesitate in writing to us. I will be happy to answer your queries. Wishing you good health. Take care. </s>
