My wife, a 46/yr old white female, has had this excruciating pain in her left arm. She describes it as a shooting and burning pain. It sometimes travels to her legs and neck. She has had numerous tests with nothing to be found. She has had a nerve test, a lyme disease test, 2-MRI's on the head and neck, she saw a neurologist and he tested her for MS and anything else neurological that may have been causing this pain... found nothing. My wife has had this pain off and on for the last 3 years. Recently -- it has been coming back more frequently and with greater pain. Now the pain had gone away for the last month -- but has just came back in full force. This pain disables my wife's use of her arm. She cannot live like this anymore. Can anyone help?
