I totally understand. When I see a new doctor I tell him I want a bone replacement from the neck down. I have a new hip, some movements cause slight discomfort, I need both knees, have had a spinal fusion still can't walk or stand for long with spinal problems.
The pain from your waist I think you said sounds, like sciatica. Have you tried cortisone shots? They work for me in some areas. I also have a bad thumb joint and shoulder joint.
I really get frustrated with TV commercials that say just take this (tylenol etc.) and your arthritis will be fine. Yeah right!
Sometimes you maybe need a new doctor. Good luck!
