Please discount my reply because I work for a chiropractor.
We successfully treat lots of folks with PF. There are several therapies that are useful....I'm sure Wahine can explain them better than me....I just work the front desk. there's ART (Active Release Therapy) (the DC that I work for is not a "licensed" ART (little trademark thingie) therapist. But he does a manual therapy that is essentually the same. its a deep tissue massage while moving the muscle/tendon/fascia through it's range of motion (kindergarten explanation). also, muscle stimulation combined with ultrasound is very helpful.
the thing with PF is to not let it go on.....get treatment early. it can be a bear to get over and seems the longer it goes on, the longer it takes to get better. the way it was explained to me is that it would probably get better on it's own, if you gave it complete rest until it was healed, but that could take months.
