it comes and goes as it pleases. Feels like sharp wooden splinters are stabbing at me. then...it goes away. DH asked on vacation "why are you walking like that?" embarrassed I had to tell him. From then on, he tried to walk behind me to cover what I was doing. I told him I didnt care what others thought, just come walk with me. He shrugged and said ok. I stopped caring what others think a long time ago.
