For a few days, I have been getting warm/hot sensation in my lower calf and sometimes foot, but the feeling migrates around rather than spreading. It comes and goes and is not severe, but feels like I m suddenly standing over a heat vent. The skin is not hot to touch, nor is it discolored in any way. By all appearances, it looks fine. There is no pain, just warmth. I am a 47 yo female and in generally good health. Do people get hot flashes in small, localized areas?
