So another heel wants to heal the heel. PF can be a real pain in the arch.
Here's my wisdom. To heal PF, you need to:
1) Stop re-injuring it
2) Reduce the inflammation, and maybe break up scar tissue
3) Stretch the foot, as well as calves, achilles, and other linked muscles/tendons.
4) Strengthen the foot
The tricky part is finding the right balance to stretch and strengthen, without re-injuring it, or you start all over again.
I would not take 3 Advil 4 times a day to reduce inflammation. Actually out of personal principle, I wouldn't take that much of anything that many times a day for any reason short of life threatening illness.
But in any case, not that many a day, and certainly not for more than 2 weeks. Taking NSAIDs for too long can be bad for your stomach, and destroy your kidneys.
Bulky shoes with support are great for not re-injuring your foot but bad for strengthening it. (A strong shoe makes a weak foot, which increases chance of injury.)
Minimal shoes are great for strengthening to the foot, but doing too much to soon will injure it.
