Why do my cheeks get red and hot, and my eyes burn, when i drink red wine? this never use to happen to me. barely started happening recently.

You are: obviously reacting to something in red wine, perhaps sulfites or polyphenols. Allergic reactions can happen without any previous history. Easiest solution is to avoid red wine altogether.

Rosacea?: You may be developing rosacea, a skin disease of unknown cause. It affects about 16 million people and often affects middle aged females of fair complexion. Many triggering factors are known including red wine. I recommend the website, www.rosacea.org, which is a national organization devoted exclusively to people affected with rosacea. Also, a dermatologist is an excellent physcian to evaluate.
