The point here is to Watch Out for tingling and numbness. The fact that I and other people don't necessarily get worse but can get better through exercise indicates that pf and tts can blend into eachother and that it is perfectly possible to have mild nerve impingement and get better through exercise. Other people on the message board with more severe nerve impingement are now pursuing foot exercise, yoga, and massage and it will be interesting to see what their results are.
I believe that mild tts may accompany more cases of chronic pf than is recognized. I find the post by john c above very encouraging for thse of us who have this accompanying condition. But do be careful with numbness and tingling. My exercise regimen DID NOT include working through the tingling. I always eased off, and found that by my showing good faith the tingling agreed to ease off too.
