I was rear ended n hit my head pretty hard and ever since then I have been havin the hot flashes in my head some days I will have them every half hour to 45 minutes all day and all night I don't get a whole lot of sleep the doctors not really sure what is causing them I tried to get him to 2 refer me to a neurologist but he said that's not necessary even though he doesn't know what's going on he said that it's probably post concussion disorder that can last up to 3 months he just gave me a medication to try to help with the hot flashes flash I was just wondering if anybody else has ever had this kind of issue so that I can kinda get an idea of maybe what's going on starting to really freak me out and its very annoying annoying
