I had a BAD case of it about 5 years ago. PT, infrared heat therapy, that darn sock , rolling my foot on frozen water bottles and tennis balls and custom orthotics all helped cure it. And it hasn't returned. Thankfully.
My friend went into a cast for 8 weeks (instead of undergoing surgery because hers was so bad) and she's not had a lick of trouble since.
That PF is a crazy little bugger!!

Hope everything works out for you. I'm back to running and doing everything I used to. You'll be back in no time!!
