Ah, plantar fasciitis - my favourite subject!
How long have you had it? Most cases fix themselves in under 6 weeks. Have you been to a GP or podiatrist about it?
It seems there's no one cure that fixes everyone when it comes to PF. I know people who have sworn by taping their feet, but that was useless for me. Rolling the sole of your foot on a tennis ball or golf ball is supposed to be good, but it didn't fix mine. I made a pair of strassburg socks
to keep my feet at a 90 degree angle while I slept. That way the plantar fascia is stretched while it repairs overnight. Otherwise when you stand up the next morning you simply re-tear the areas that repaired overnight (which I think is why it hurts most in the mornings).
The things that fixed my PF are switching to FitFlops
and [ur=http://www.crocs.com.au/l]crocs[/url] for everyday walking shoes, and a special stretch which targets the plantar fascia (here is the link to the news article
, click the show transcript link. Instructions on how to do the stretch are contained in the transcript).
I still have some bad days, but I got back to running 5km which I was pleased about (until I strained my back which is another story entirely!)
Good luck with your PF!
