Sorry to hear you have it, I had PF for about 14 months. It definitely sucks. I tried almost everything (pretty much everything short of surgery). Mine is finally gone, and I'm back to running.
For what it's worth, here's my observations / experiences.
- it doesn't just go away on it's own, and you can't just gut your way through this injury. This is hard to hear for someone who likes to run...but the running has to stop until the pain is totally gone for a week or two...and then you start back SLOWLY. Ignoring this just makes you have a prolonged time away from running.
- icing and NSAIDs are good to reduce inflammation. I liked using mini water bottles, put them in the freezer and use them to roll your foot over. I did this 4-6 times a day (I have a mini-fridge in the office, so I could do it at work pretty easily)
- golf ball under the foot makes for a good foot massage and helps break up the scar tissue. Hurts at first, but eventually you can work your way up to actually standing and putting a fair amount of weight on it as you work it back and forth.
- tight calves, lower back, thighs all can stress the facia and you should stretch these areas out. Rollers work well, and are also considered torture devices in most 1st world nations.
- Boots and Stausburg socks helped to keep it stretched over night and reduce pain in the morning, but didn't fix things for me on their own. They also suck to sleep in. I wore mine after the kids went down when watching TV and as many nights as I could stand.
- choice in footwear makes a big difference, get professionally fitted (and not at foot locker or Dick's sporting goods). Cheap shoes (not just running shoes, but everyday shoes) were a big part of the problem for me.
- Insoles are key. I tried the green superfeet insoles and they didn't work for me. Tried other over the counter ones, they didn't work either. I had to go with custom fitted orthodics.
What finally solved the issue for me was to suck it up and pay for a specialist to mold my feet. They were expensive, and I got ones that would would stand up to a lot of abuse...actually they are made of kevlar. After three weeks of wearing them (every day my feet felt better and better) I was confident enough to start trying to run again. Started at only a mile to a mile and a half every other day for about two weeks, and I'm back up to about 25 miles a week again after three months. Like I said, start back SLOW.
I also bought a mountain bike and biked for cardio when my feet were bad. Being sedentary sucks, and it helped keep me from going nuts if I couldn't run.
