@cmzollinger - No wonder you are frustrated! I only experienced real improvement when I started seeing a physiotherapist - who is like a regular PT but with a deeper whole-body understanding. I use simple orthotics for brain retraining and I use activator poles when I walk long distances which helps both steadiness and core strengthening. I still hate walking down steep steps.

Hang in there. Spinal issues take a long time to develop and they can take a frustratingly long time to improve. Never give up. Maintain a positive outlook. Try new things. Be experimental (what do you have to lose?).

Good luck. Positive energy being sent your way...
