Why does the left side of my face turn red when i drink alcohol?

No clue: Many people flush with alcohol, particularly people of asian background, including native americans. However, that flushing involves the whole face, and I do not know why you would only have the left side of your face involved. Flushing is a sign you are creating more of the toxic alcohol metabolite acetaldehyde, and is a clue for you to reduce your consumption.
