Snake oil is a remedy that is sold for a condition that does not work any better than a placebo. How many remedies that are ‘sold’ for plantar fasciitis don’t work better than a placebo? There is probably a lot.
The biggest problem with plantar fasciitis is that the natural history of it is to generally get better on its own. Just look at the placebo groups in the clinical trials to see how many do get better on their own without treatment. The only reason to treat it is that is hurts and can take a while to get better on its own. The problem with any treatment given, the question is that did the treatment work or was the plantar fasciitis just get better on its own at the same time as the treatment was started. that is why we need to rely on good randomized prospective clinical trial to sort out the treatments that don’t work better than a placebo vs those that do work better than a placebo.
For this reason there are so many plantar fasciitis snake oil salesmen on the web. You can see plenty of eBooks and secret sauce treatments that “the doctors don’t know about” for $19.95. All they have supporting them are plenty of testimonials that you have no idea if they are real or not. There are certainly no clinical trials supporting them.
Plantar fasciitis treatment is easy:
Start by reducing the load on the damaged tissues; then do things to facilitate the healing if there is not an immediate response; and then progress to the progressive adaption to increasing loads
Don’t fall for the snake oil salesman. Get it treated properly.
