I think I am getting hot flushes. Some seem to be pretty classic (I have had hot flushes in the past due to some medication that brought on a temporary menopause so I remember how they felt): These start in my face, and spread lower, and only last a minute or two.
But I am also getting burning, hot cheeks (facial!) and I am not sure if this is a hot flush. It can last for hours, and my cheeks feel hot to the touch and look red too, but it doesn't spread elsewhere. Not related to drinking red wine 
I also find that I get loads of hot flushes some days, and none or very few on others. Is this usual?
