I have read that the longer a nerve is impinged the less likely it will recover fully and the less immediate relief you can get from surgery.
If a nerve is impinged/getting nerve pains for more than 6 months shows irritation and/or impingement, your chances lessen, and the longer it is the more chance you have of permanent damage. Some people acutally can get drop foot with nerve impingement also, where the muscles when they walk cannot lift the foot near the ankle, and other things like that. Its not a fun picture.
Emergency surgery is just that- emergency- unless you have problems urinating or holding your bowels, emergency surgery is unlikely, AND who would want a surgeon they DONT know, operating on THEIR SPINE- not me. I liked getting to know my surgeon, trusting him, and getting my surgery at my own pace scheduled and mentally ready for it.
If surgery has been brought up, it will be needed one way or the other, its just your choice how long you try to wait, and how long you are ruining the nerves to the point they can't recover. My nerve was impinged for 9 months total, I still have nerve pains, and am on neurontin (helps block the pains), doesnt do it 100% for me but, better than nothing. Only time will tell if the nerve will recover. I had surgery in October, reherniated immediately and no one knew nor understood why I was recovering so poorly, had another MRI 4 months later, nerve impingement and severe reherniation, and had a fusion 8 weeks ago.
I didn't CHOOSE to wait for surgery, its just how it wound up, and the nerve impinged so long. SO just gotta wait and see for me how much my nerve recovers, but the impingement is now gone so no ongoing damage, just residual damage thats got to try and heal.
