I have the exact same problem. I'm post menopausal and used to get hot flushes, then i didn't get them for ages, now they are back. I've just got back from a pilates session and i walk there. I always get comments, like you have already warmed up etc. I thought it might be niacin flush but stopped taking anything with that in because some people are sensitive even at low doses. Even when i don't flush i can see the capillaries under the skin. I've started taking maca root. This is supposed to balance and nourish the whole endocrine system. I was trying to find a cream and came across this website, so will try that boots anti redness cream that has been mentioned. People are so insensitive. It really does impact on your life. People think you are blushing with embarrassment don't they. I have to push myself to go out and do normal things, because i fear flushing. It can become a phobia if you let it though. I know what you mean about you can be sitting on your own or in my case talking to my husband, and the flush comes, so its not embarrassment, but can turn to that, if people keep pointing it out. I try to ignore it. I'm going to take driving lessons, but fear flushing so the cream might make me feel more confident and not so self conscious
