Overview
Flushing is temporary reddening of the face, neck, or chest from widened blood vessels. It's common with heat, exercise, emotions, alcohol, and spicy foods.
Rosacea is a long-term skin condition with redness on the central face, flushing, visible blood vessels, bumps, and sometimes eye irritation. Lupus can cause a butterfly-shaped rash across the cheeks. Rarely, frequent flushing with diarrhea or wheezing can come from hormone-producing tumors.
