It takes time in my experience. I had PF for about 6 months six or seven years ago , I could have written a PhD thesis on it. For me it started with my calfs after a hill session and I still continue to foam roll them regularly to avoid it. To be honest ive seen so much contradictory advice given I now rarely bother to contradict things , the things to avoid in my view are those who say “ yeah I had it for two weeks and this cured it…( yeah right not if you get PF real bad). Some things to avoid : advice to roll your foot over a golf ball - it’s an ”itis” with inflammation , why would a hard golf ball not make it worse; frozen bottles of water or ice - after the issue has set in ice won’t help much in terms of healing , it may feel soothing at best. I actually had Chinese acupuncture in the end , very painful , took 5 or 6 weeks but helped to break the back of it as nothing worked on its own I was doing taping , foam rolling , stretching etc. Good luck.
