did you ever get checked out for plantar fasciitis? your symptoms resemble symptoms of it. i got it one time in both feet at the same time. one morning i woke up put my feet down and almost went through the roof. very painful and i couldnt walk. i thought that was it that PN had destroyed my ability to walk. very unusual to get both feet at exactly the same time. the left one released by itself while going down steps. i had to get a shot of cortisone in the right one to get it to release.
