My lower back is junk

You’re not old at all, don’t wait too long to have it fixed. I just had my surgery on my lower back and I refused to have my back fused like my neck. They did have to cut away some of the disc and remove part of the outer bone but I feel better after 40 years of pain, numbness and tingling.
I learned never to fuse anything, the ex had a fusion, and what a pain that was.
