Hi everyone

This has been bothering me for as long as I can remember, and although it's relatively unimportant I'd love to find out how to stop it. At random times, the palms of my hands and soles of my feet will become
extremely hot, as if I've been holding them over a fire. The heat's definitely not just my imagination, as I've held people's hands during one of these periods and had them comment on it. It's not painful in the slightest and there's no sweat, but it can get quite irritating and uncomfortable, especially if it happens in someplace like class where I can't immediately run and dunk my extremeties in water. I'm sure it's nothing serious, but as I said it's quite uncomfortable and I'd love it if someone could help. Thanks for reading!
(Also, I am not sure if this is relevant or not; I'm a 17 year old female with no major health issues besides being a few pounds heavier than I'd like- but then again, who isn't?)
