I have been having increased lumbar back pain for 2 wks. I had a micro-d in May. Since then I have been on Vicodin, Naprosyn, and now Arthrotec. If I over do it my back starts burning not to mention PAIN!! My surgeon says I need to have fusion surgery because I have barely any disc left due to 3 herniation at L5-S1 and the surgery to remove all the fragments. Anyone have burning sensations in their back? What is it?
