I had a lumpectoy in June 05 and they removed 5 lymph nodes. I am having terrible shoulder and elbow pain in my arm on that side. I have been to so many doctors. They have ruled out arthritis, bone cancer, pinched nerve, muscle spams...... I got off the Tamoxifen and started taking Celebrex which has helped some. I have taken muscle relaxers, pain pills, etc. I am still in tremendous pain and was wondering if I could have scar tissue that has built up under my arm from the lymph node surgery that could be tangled up with a nerve or muscle causing this pain. Today, my arm almost feels numb like the blood flow is being restricted. Can an X-Ray or MRI show scar tissue?
