I have a question for the board. I am a high school runner, and experience an uncomfortable burning sensation on my feet while running. This only occurs while running. My feet also sweat a lot when this happens. Does anyone on the board have this problem, know what causes it, and hopefully what can be done about it? I am otherwise healthy, and my doctor can't figure it out. I have tried foot powder, wearing different kinds of socks and no socks at all to no avail. Thanks for the help.
