>>Actually, the pain in the right foot came during the 3 day of fasting, but it was negligible then, becoming stronger and stronger as I was breaking the fast.
All fasting books recommend that you don't break a fast in the middle of a healing crisis. You wait for the healing crisis to pass. You did a big no-no.
Sorry, I'm not experienced enough to know how to fix it, I just know that you shouldn't do it. Maybe I can look it up in one of my books...
