Plantar Fasciitis
Plantar fasciitis is the life blood of so many podiatry clinics. It something we see day in and day out. It is the most common musculoskeletal problem seen in the foot and I suspect that for every case we see, there are several others out in the community not be being treated. If its painful under the heel and if it worse after resting (ie sleeping) for the first few steps then it is probably plantar fasciitis.
The most appropriate treatment for plantar fasciitis is stretching and lots of it. Foot orthotics also help a lot at reducing the load in the plantar fascia. There a lots of secret sauces, miracle cures that you can buy, but there is nothing secret or magical about them! But it all comes down to stretching and reducing the load in the plantar fascia. Run Junkie probably has the most sensible approach to plantar fasciitis that I have seen.
