I know what you are going through!!!! You name it I think they have tried it on me. I also have had 2 heel spur surgeries the last they removed the whole spur, with no relief. I am at the point where I can't even make it throught the supermarket in one trip.I can only stand for about 15 minutes at a time (and thats pushing it) before I have to sit. I have fought these feet for so long, I don't know if there is a light at the end of tunnel. Good Luck with yours.
