I had a fusion in L5 S1 4years ago. Before my surgery I was having low back pain, or it felt like low back and down through my right buttock burning really bad in my buttock. I had the fusion and still have the burning in my buttock. It feels like my low back but when i lie there and concentrate on the pain it feels mostly like my right buttock. I feel absolutely horrible most the time. I went from cycling, playing sports, scuba diving, to mostly lying on this huge bean-bag on my stomach. When I lie on the bean-bag on my stomach the pain goes away, but soon as I get up it comes back. I have been dealing with this since 1999 and held out as long as I could stand it to have the surgery. I have had MRI all kinds of scans and test including one with die in my spine tilting on a table for them to get good images of everything. No one seems to be able to find out why I hurt. Was hoping someone out there had similar symptoms and has found out what it is. Thanks for your help.
