Hi I have chronic SI Joint pain and severe sciatica. I injured my self about 24 years ago in the swimming pool and have had a sore pain in my left buttock ever since. I had an operation to see if there was a trapped nerve, but this did not work and when I woke up from surgery I had a 10 inch cut on my left leg. Since I have had 3 fractures in my upper spine in the last 3 years, and I am now very bent over like a very old woman, I am only 70 years old, but 21 in my brain. I asked my Pain specialist if I could have a implanted nerve stimulator fitted, but he said that was not possible due to my fractures. Does a pain pump get fitted the same way, through the spinal cord (i e wires inserted inside the spinal canal and up to the brain, or is it just fitted where you have the pain locally under the skin and next to where you feel your pain i.e SI joint? and how do you get the medication into it? Is this inserted some how outside the body, or is this done at the hospital. Any advice would be very welcome. thanks
