I have just had my nerve fusion on Tuesday 1st November in my hips/ lower and middle back. Has anyone had this operation and could they let me know how long the pain last? I have no pain now in my hips or the right side off my back but I still have the pain in my left side. I had the operation all done at once there is a lot of people go for this operation in two parts. When I woke up in recovery I was in excruciating pain and they put me on morphine and liquid paracetamol which helped a lot with the pain. I just would like to know if the pain will settle in my left side of my spine as after the operation my hips and right side of my spine is fine. I would appreciate anyone who has any knowledge on this type of operation to let me know How long it takes for the pain to go.
