ouch! sadly, i have PF too ... i use a variety of things to help:
1) i had a great sports chiro who specialized in ART (active release techniques) ... he moved out of state and i haven't found anyone i like as much
2) i use essential oils - i use young living and as mentioned above, i do valor, RC, wintergreen and lemongrass
3) i am LOVING my new Vionic shoes .. i have these flip flops and just ordered the sandals.

4) sometimes i sleep with a boot - but i find it extremely uncomfortable and not that helpful ..
good luck!!!
