<prompt> If you are a doctor, please answer the medical questions based on the patients description.Went to massage therapist in late July and she was a little rough when she was massaging under my left arm in the arm pit. For 2 weeks, my left arm was weak and I had no strength in my arm. On labor day of this year, I suddenly had a pain in my left side and from that day till now I have been in pain. I have no use of my left arm, and very little use of my right arm I had use of my right arm until then and had been using my left arm until then. I have been to the doctor, had 4 MRI s, a CAT scan and am now seeing a Neurologist. They can t seem to come up with an answer. I have been out of work for 6 weeks. A friend in the medical field asked if I had been to I had MS, I haven t been told. I get confused when trying to look up the symptoms. Can someone give me some information?  <response>: Hello, I have studied your case. . Pain indicates inflammatory process or nerve compression. I will advise you to do PET SCAN so that lesion in any area of body can be identified. I will advise you to do EMG-NCV study. Till time, avoid lifting weights, Sit with support to back. You can consult physiotherapist for help. 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.
