Have I got Rosacea?

Patient: My dermatologist said my rash from the sun was rosacea but my GP said she would put money on it that it wasn’t. I am now stuck, I am 24 and have a rash on my forhead, inbetween my nose and on my cheeks. I wore a high factor and it only came out when I started drinking. It is quite itchy, red and bumpy.
