I can certainly empathize with you.
I've had back problems since I was 15 when I broke a vertebra.
Seven years, and a lot of pain pills and therapy later, they did a spinal fusion.
They chiseled chunks of bone off my hip and packed it around the break to form a gristly mass.
It worked, but I still have frequent problems, pain and sometimes weakness.
I did my job to the best of my ability and kept my off-days to a minimum.
I just retired from my job and am eternally grateful I never have to climb another telephone pole again.
Keep at the therapy and do as much as your body will allow.
Photography is a great mental and physical escape at times.
Enjoy life to the fullest!
