@heyjoe415 thank you for replying it is nice to have the support ! I went to Dartmouth for my knees and they said there are like pot holes in the patella which aren't bad enough for a full replacement. I could push for a patella replacement but the other parts are showing partial wear and I think they will need replacement in the next few years so I am just going to wait. The PT has helped the knees it is just overall systems issue at this point ! I agree it is neuropathic on the foot and sometimes the full leg is heavy. We will see if the brain MRI shows anything - that will be the final test and then I will just manage until the parts start to wear out. I have bad reactions to cortisone so try to avoid that.
