The short version-could I possibly be doing irreprable damage by refusing to act on this stuff?
Long version
I had my most recent MRI at the end of September. My GP wanted me to see a surgeon immediately-one I'd already had a bad run in with 3 years ago regarding him wanting to do surgery on me within 15 minutes of seeing me (after reading my mri report and taking a few x-rays) and me wanting to try non surgical methods first. He told me there was nothing he could do for me if I wouldn't go the surgery route, I asked about pain management, he refused.
I went on my way for awhile, but after the first year I was in major pain and nothing I did on my own helped, so I went to my GP to see if he could do something. He's been helping me with pain management-at first vicodin and skelaxin, now with vicoprophen and flexeral, which seem to help more than the first 2. He's offered percocet but that did absolutely nothing other than occasionally making me sick.
My knee doc requested a copy of the most recent mri and said I need to see PM if I won't do anything else and that the results explain the pain and problems walking/standing that I'm having. He thinks I need to have the rest of my back looked at as well since the numbness and burning I'm getting in my hands and arms and the clicky feeling in my neck might be related to my back.
So, am I being stupid by trying to bury my head in the sand because I'm afraid? Is it possible that I could do permanent damage to my back by Not having surgery?
I know the medical opinion... even if I don't want to hear it. What I'm looking for is opinions from people who have a lot worse problems than I do now... would you consider surgery, even tho' it's likely to fail? Is it possible for me to get some relief without doing something drastic? Would an epidural shot be possible if, during previous surgery they were unable to do an epidural because there wasn't enough room to get the needles in (they tried 8 times ;( ) ?
Surgery scares me for a lot of reasons, not least that I am my mother's primary caregiver...I can't just take to my bed for weeks or months, I work full time, tho' it's getting harder and harder not to miss too many days... every time I think or hear the word surgery I shut down.
I am afraid of what I'll hear if I follow up on this... but I'm also afraid that I am fast getting close to the morning where I just won't be able to get out of bed. The back and leg pain are getting worse... my walking is getting worse, it seems that the only thing I can think about lately is my pain... which makes me a pretty dull friend and family member I guess.... 
any suggestions on how to get my mind around this? how to motivate myself to actually do something....anything to move this along?

I believe your reaction is normal to the idea of surgery. No one should openly want it or the are just ignorant to the possible outcomes of it but with that said you have to approach your situation with the highest chance to improve your quality of life. Yes easier said than done.
It would seem to me aleady several docs said you must have surgery. I would try and find a doc you really trust and feels has your best interest in mind. Than really listen. Most docs to not immediately go to surgery and will try all means to do it non-invasive.
I think you have to ask yourself honestly has life gotten better or worse in the last 6 mos? Do you see any signs of recovery? What are you doing to help it? Than maybe sit down with your family and see what you should do. You can not always be the martyr.
I think you need to step back, breath and really look at your situation and than make a plan of action and try your best to follow through with it.
