I'm a 34 yr old female, healthy, physically fit and when I'm nervous, warm or just whenever my nose will get bright red out of nowhere & I can't stop it. I noticed this several years ago when I was cold or hot but in the last maybe year my nose will get VERY red & it's embarrasing. I've tried to tilt my head, put ice on it...everything I can think of & it just comes and goes as it pleases. Sometimes it's accompanied by a very warm or flushed feeling & my whole face feels warm. Other times I don't even know it & I see it in the mirror or someone tells me. I will have a few drinks on the weekends when I bartend and I know people used to tell me about a year ago when I would drink. However, now it happens during the middle of the week when I haven't been around alcohol or dramatic temperatures. I ask for any help you can offer as it's become very embarrasing.
