I'll repeat my experiences..... while we wait for Karen's answer.

Nightshade veggies--- really cause burning feet for me. Potatoes are the worst, then come concentrated tomato products. All the peppers upset my GI tract...even paprika.

Red wine and white wine, and MSG (monosodium glutamate) also bother me. Chinese restaurant food...ugh! I even get blurred vision from MSG.

MSG is an inorganic form of glutamate which floods the blood quickly when absorbed. (glutamate naturally in foods has to be digested to be absorbed--and this is a slower process). Then this glutamate goes to the NMDA receptors among other things, and may trigger them... NMDA =pain

Sugar and ice cream may increase burning too, by thickening the blood.
