Ive been having numbness and pain in left pelvic area and lower back pain due to mild herniation of right lumbar region from work injury. Had 2 injections and PT, went back to work then started feeling pain and numbness down buttocks in rectum. Numbness after a BM , had MRI cat scan , Emg, all seem normal except mild herniations, doctors can t.figure out what s causing numbness AND pain. Is.worse with sitting down and lying down, after extended physical activities, etc,, could this be.caused by herniation pinching nerves or possible pudendal nerve
