One of my manifestations of TMS has been in my heels. Specifically, it felt like it was where the Achilles tendon would attach to the heel. It was relatively short lived for me...a matter of weeks instead of years, but it was the first painto go for me :-)
If you're talking about "plantar fascitis" yes. Sarno and Sopher, especially, regard it as TMS. I've had it for quite a long time, but it doesn't interfere with my running marathons so I try not to worry too much about it. As I mentioned elsewhere, PF has the irrational no rhyme nor reason quality to it that is typical of TMS. In my case I think it is likely there is a strong psychosomatic component to it, but I'm not yet at the place where I can say it is 100% TMS.
