Worried I may become paralyzed

After 7 years of having stenosis and finally having a laminotomy two and a half years ago I'm back to square one with the pain returning. Laminotomy only works for 3 months. At this point too surgeons have done epidural injections determine which level of my spine is causing the pain. So far the injections aren't helping anything so I am wondering does that mean surgery won't help and if surgery won't help what is my future? I have throbbingg after I walk. I feel my pain is getting worse every year and I was told I should do usually about a year ago but I didn't and now it seems like I might have waited too long and not even fusion will help I'm getting very worried and don't know what the next step should be. And send me any advice / doctors who can work on extremely difficult cases or perhaps hopeless cases.
