Glad you're having fun on the bike!

Best thing for PF is trigger point work. Hurts like f@#$, and I can take a LOT of trigger point pain. But totally worth it. Get a spiky roller for your feet and do it whenever you're sitting or standing - or just walk around barefoot on gravel every day.

Hope you get it under control soon. Do make sure you're not plantar flexing when you pedal, because that can be as bad for the lower extremity fascia as anything you can do on foot. DAMHIK.
