I just edited the intro secn of Blushing and added the next secn; i also created the stub Flushing. I (so ill-suited as to even forgot to link Fever!) am leaving to some non-amateur observer the task of determining whether the next two secns of Blushing should perhaps be broken out as, say Erythema, and linked by both of these articles. And of course the same person could add to Flushing (physiology) at least some common disorders that have it as major symptoms, or better, characteristics of flushes that justify professional triage or Dx.
