I have been having acute pain & numbness in my right buttock, thigh and leg for 6 months or more. I have had an x-ray of my back and it did not indicate anything. My insurance company will not authorize my doctor to schedule an MRI. Some time the pain is in my leg only and is so severe I am unable to sleep. Other times the numbness is in the thigh and buttock and is not accompanied by any pain. I have been on muscle relaxers and prescription Aleve but they do not provide consistent relief. Can some point me in the right direction for possible cause & treatment?
