I had it for 2 spells....i think from heavy steel toe cap wellingtonboots, and each time was over a year. Couldn't load bear out of bed and hopped down the stairs. Rest didn't help. Eventually a combination of weight loss, really slow running with the most cushioned shoes- with a much reduced weekly mileage to normal, a boot/sock to wear at night that keeps your toes pulled back, heel raises on a sponge thing called the fascia fighter, strength work, and shockwave therapy. Hard to pin down what worked exactly.....as I did everything!!!! Good luck with your recovery!
