I Get These Weird Flashes, Not Really Hot Flashes, Feels

I get these weird flashes, not really hot flashes, feels more like an electric shock. I have gathered that the higher the temperature, the more likely it is to happen. It just happens for a second or so but sometimes it will be every 10 seconds. I don't pass out or anything, but I do have some trouble. I will have to hold the wall or focus really hard to stay standing.
