I personally had a fusion and have had good success. I was having a lot of nerve related issues (nerve compression causing foot drop and actual loss of feeling to my foot), I noticed improvement to the nerve related issues almost immediately. I am walking up to two miles a day five days a week and have settled into a regular streching regiman. Though, I have to say certain things I do I still feel in my back and I do have to watch myself, but over-all I would say I am about 80 % improved over what I was before surgery. I have no experience with ADR, however I know many people on the forum are going that route.
As far as emailing, my understanding is it is not allowed on this forum and that is probably why you couldn't do it (we are an anonymous forum; it is in the posting rules and regulations). I hope this helps!! I hope you get the information you need!!
