Hi, I was wondering if anyone could help diagnose this problem.

Whenever i'm in remotely cold weather, my nose turns extremely red or sometimes purple. I don't mean below freezing cold, but anything below 55 degrees (f) seems to make it happen. The symptoms look a little like rosacea, but it only happens when i'm in cold weather.

I understand lots of people get red noses when they're in the cold, but a shade of purple doesn't seem quite normal, nor does the severity. Once I get back into a warmer building the symptoms will eventually subside, so I think it must have something to do with the blood vessels in my nose dillating or something. Could this be an early sign of rosacea?

If anyone could help me out I would appreciate it.
