Hi.. maybe you should do some reading about Erythromelalgia - there is an online association for this.. Some of your symptoms seem to point to it, in my humble opinion.. I suffered from this issue for many years, until my feet turned to neuropathy.. I continue to use a rubbing oil that I get from Amazon on my feet when they get hot and red, usually when I go to bed at night. Called.... Neuropathy F & M.... the f&m is Frankincense & Myrhh... Many diabetics use it for their neuropathy and that is how I was turned on to it.. Not expensive either, although it comes in a small bottle and includes an eye dropper. I was taught to mix a few drops with hand lotion. My husband won't let me ever run out of it.. Some folks do have the problem on their face and ears...
