Coffee in excess, wine, or any type of alcohol, stress, upset, anxiety, all of those can trigger me to that very same feeling, although I have the bonus of looking in the mirror and all I get for the forest fire on my face is a mere blush on my cheeks.
This feeling does pass more as you stop your periods, but wait, there's more

then you burn up all over in one foul sweep that usually lasts from a few seconds to 5 minutes. Even the full on flash does not make me appear reddened, and then I take my temp, and if anything, it's slightly below normal.
There is one consolation to this. Now and then I get a day where I have NO flashes. This does show that there is light at the end of the peri tunnel we are all caught up in.

What you are feeling is a prelude to the real flashes, so if they appear to get stronger, don't get scared, just realize what it is, and try and breath your way through it.
Excercise also helps in keeping flashes under control. I don't know how or why, but it just does.
Take Care,
