I have similar problem. 84 and 3 surgeries 30+ epidurals . I have taken percocet for 20 years. I refused spinal cord stimulator. I still have pain,but can get around at home and with help to a restaurant. I use a 4. Prong cane and am currently thinking of using my walker more to walk 2 blocks. I have used physical therapist so I don't get worse.
