My PF 'has' gone away. But I just know (and from speaking to 2 friends who've had it too) that my footwear has to be rethought now. I can't wear my beloved Adidas Gazelles anymore even with an orthopaedic insole as it can get painful and make the PF flare up again.
I've had to give up running/jogging as I don't want to risk PF flaring up and I think running/jogging plus partly returning to work and wearing trainers and then work shoes caused the PF in the first place.
But tell me how you started running with PF again? What did you do? I think I warmed up but forgot to cool down.
