I am new to this website. A year ago I had revision scoliosis surgery, which included fusing S1. Immediately after the surgery, I began having pudendal nerve pain, which included pain in the ishial tuberosity (sit bone) when sitting and pain and burning in the vagina. I would like to know if anyone has had similar problems. I would also like to know if there is any research on reversing lumbar fusions and implanting something a little more flexible.
