I Have Drop Foot In My Left Foot From Damage

I have drop foot in my left foot from damage when I had a spinal fusion.

















































































I have drop foot in my left leg and foot from damage done in a spinal. I wear a AFO brace and walk with a cane. Is there any alternatives that can be done for the pain. I know my legs are getting weaker. But I am tired of taking medications and I have been through a lot of physical therapy. Any suggestions?
