More weirdness

A year ago last summer, I got a red rash/discoloration on my lower legs. Later my doctor in the U.S. said it was rosacea, and gave me some anti-biotics to get rid of it. It worked, but this fall, it started to come back again. So I guess we can eliminate the late unlamented Kaohsiung 前金游泳池 pool. Anyway, this time I stopped drinking (instant) coffee, and it's started to fade. But rosacea on the legs? It seems pretty weird to me.
