I had a bad case of pf because imo i continued playing for about 2 or 3 months after getting the first symptoms, my suggestions:
1. Stop playing totally
2. Treat symptoms
3. Treat cause <---
Usually people stop at 2 and fail, you have to go to 3:
Normal causes of pf are usually tight calves or/and weak foot muscles
You should do stretching AND
streghtening or your feet not only stretching
There are numerous videos on youtube for both
What i did:
1. I stopped playing for 6 weeks take or give
2. Took motrin for about 3 weeks then stopped
3. I got another pair of shoes, my barricade 6s were just too stiff
4. I bought heel inserts (The gelly ones) to treat my heel pain for the first 6 weeks, dont use them anymore
5. I bough superfeet green for every shoe pair, use them everyday <-- this helped a lot
6. Im also buying some socks for the night called strassburg socks
6. I do 5 sets of stretches and 5 sets of streghtening everyday:
a. I stretch against a wall doing this:

b. I strengthen doing this:

Hope it helps
Other usefull tips:
1. Dont walk barefoot, always wear shoes with superfeet or good arch support
2. I have a cushion which i place just where i take my first step in the morning so instead of stepping in the floor i step in the cushion
