Wow, you have a LOT of pictures.

I thought you might be interested to hear that last year I could not lift my feet. Similar to when I had tetanus and it took me three steps to cross a foot-square Saltillo tile. I was really worried. But a lot of rest and very gradual exercise has made for amazing improvement.

Have you checked out the symptoms of low vitamin B12? B12 is often a factor in neurological problems.

Tetanus, as an aside, is a central nervous system disease.
