What causes burning sensation on feet?

Well it sounds like a pinched nerve.Years ago I had same. it turned out that I had tarsal tunnel syndrome.Which is similar to carpal. Also may be peripheral neuropothy. Common in diabetics but can be "idiopathic" or unknown. Can be isolated to one area of hands & or feet. But, may also appear in face and jaw. Regardless a burning sensation is most likely nerve-based as previously posted.
