Hi. One of my docs was talking about this stimulator for me. Right now I'm not willing but at my next apt with some new docs I will talk about it. I understand and hear your fear. I was also suggested and they really wanted to do it and said very little side effects. Is a tunneled epidural catheter. Its gives med through the spine. For me this was to be able to do extreme reabilitation on my legs and is only in for 6 weeks. On another note and may look into this is acupuncture. I'm not into alternative stuff but at this point I may try it if not in my legs. Good luck in your choice. I understand on how hard it is. I hope you feel better
