Hi John, I have had 4 spinal fusions over the last 12 years and have chronic pain from 2 of those surgeries. But I the last 3-4 months I have developed small nerve neuropathy in my legs and it’s extremely painful at times. I am undergoing blood test for autoimmune diseases right now and also having a CAT scan of my chest tomorrow. The medications that I’m taking are helpful but they certainly don’t take the pain away. I also have four compression fractures in my thoracic spine recently had a kyphoplasty and then they intercostal nerve block which seems to backfired. I am 67 and was very active and athletic .
