I have a trapped nerve in my back that causes pain to shoot down my arm. Ibuprofen does not to work. How can I fix it? How can I relieve the pain?

Surgery. If it is a trapped nerve then an anti-inflammatory drug will decrease inflammation but not fix the nerve. Surgery will fix the trapping. I would have a physical therapist work to make certain it is not an issue with a muscle group - and then see a neurologist.
