I've been having burning pain when sitting in my buttocks around the pereneal area and the back of my upper thighs. I've had this for five years. All diagnostic tests have been negative, but I do have degenerative disks in my lumbar region, but with no stenosis or significant back pain. I have been on Neurontin, Pamelor and Oxycodone and have had injection therapy with no real relief. My doctor at the University of Michigan Pain Clinic is now talking about an implanted neurostimulator as a possibilty. Is there anybody out there that has similar symptoms who has had treatments that have provided relief? Thanks!
