Solutions for a red-hot face...?

i've been battling this for almost a year now. i'm 18, and just starting college, and this really (as dumb and dramatic as it sounds) is having an effect on my everyday life. my face, on the sides of my nose, and on my cheeks, gets incredibly red/flushed/hot. it looks like a sunburn almost... i've noticed it happen in conjunction with my feeling nervous, but sometimes it happens when i'm not nervous too. i can feel it coming on, and when it does, i just try to ignore it. it never skips a beat with the nervous side though. i've really tried just about everything i can think of. went to a dermatologist to get it looked at. tried many different things for rosacea. wasn't that. i moisturize every night before i go to bed. i know it's not a dryness issue. i've taken st. john's wort for probably more than a year now. i began taking it in relation to depression. i got that taken care of, and thankfully don't have any more problems with it. i still take st. john's though just to keep healthy. i began taking quercetin, another homeopathic pill that aids with controlling the body's response to inflammation. i've been taking that for over two weeks now, and still no help. i'm going to continue taking that though as well. i've tried a homeopathic pill for allergies - to keep you clear and decongested, hasn't helped. i've tried to breathe deeply when i feel it coming on, and that hasn't helped. i've tried talking to myself and calming myself down, and that hasn't helped. usually what i do is go to the bathroom, splash a little cold water on my face, and pat it dry. it relieves it for about a minute or two, but then comes back. i've also noticed it in conjunction with being in a warm room sometimes, though really, i don't think the room(s) are that warm. i've tried to look it up online and do some of my own research. i've been led to many of these yahoo ask pages, but none of them have really helped. i haven't seen anyone else with what i've got. it doesn't look like a rash or rosacea, and i don't think it is. it usually goes away when i leave class or the situation (i.e. job interview, work, hang out with family...) i think it's weird that it happens even when i'm around family members though... i'm not nervous around these people, yet it still comes up. it is highly noticeable and not just an exaggeration of what i feel/see. people have said things about it, which really just makes me more frustrated/embarrassed about it all. i wish i could upload a decent picture of it, but i don't have one. any help would really be appreciated. my next steps that i have in mind are to get an allergy test, go to a homeopathic doctor, and talk to a psychologist about it even though i'm not certain it has to do with nerves. this really is having an effect on my self esteem. i get frustrated and then down about it. also i don't want to introduce myself to people when i have it because i'm so very embarrassed... what can i do???

i know exactly how you feel, ive been suffering from red/warm face for a couple of months now, its very annoying and really uncomfortable, it normally happens to me when im at college, or if i feel under pressure or nervous, it makes going to college quite difficult, it also comes on me when i eat sometimes or when im out with friends, it has affected me and it gets me down, sometimes i chose to spend my free classes alone outside rather then sit with my friends indoors, because when i get flushed its so uncomfortable and i just want to get out of their, i was never a really confident person, but it has goten better i started not to think about it so much and try to stay calmer, i drink lot s of water and i also went to my doctor, but so far have got no help, she took my blood pressure and my thyroid but everything came back fine. i really hate it because first of all no one wants to go around with a red face and second and most important its really uncomfortable, i feel like i constantly have to hold back just incase i trigger it.

drink more water, try not to think about it, i know easier said then done, and do more exercise, they helped me.

Go to a dermatologist.
