While you have several quite small herniations, none should be causing the pain you describe.
The T8-9 "flattens the front margin of the cord" but there is no cord stenosis or narrowing. So the T8-9 isn't really doing the cord any real damage at this point.
At L4-5 with the bulge of the disc annulus & disc protrusion & annular tear abutting the nerve root -- that could HURT. Anytime we mess around with nerve roots, it does hurt.
However, I still don't think this is a surgical event. I would HOPE no surgeon would do surgery, as I just don't think it's called for -- YET. And your pain would probably NOT be relieved.
I know you're hurting, and you should probably see a pain management doctor if you haven't already. The only trouble with them is that they always want to do steroid injections -- and they rarely work.
But, I hope you find some relief. Please take care and God bless. Let us know what happens, will you PLEASE? I'd REALLY LIKE TO KNOW! Big hugs, Lee
