<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have severe low back pain. My PcP has tested me for various diseases, all negative. But he diagnosed me with fybromyalgia...I cannot hold my stomach in and moveexcercise without causing severe pain from a hemmoroids. Could this hemorrhoid be the reason for my low backhip pain ? Samanda YYYYYY  <response>: HelloWelcome here dont think that hemorrhoids can cause low back pain. Low back pain is usually due to disc prolapse. An MRI scan of lower back will help to find out the cause. Fibromyalgia can cause pain at multiple body sites. I would advise you to visit a physiotherapist for exercises to help you in back pain. Do hot compresses regularly. Keep your posture correct. Take pain killer like Tylenol when needed. Hope this helps. Thanks
