Dermatologist

I have been waiting since October to see a skin specialist about my facial rash .. rosacea and/or lupus rash .. my immunologist wants to know .. my suspicion is rosacea .. all the classic signs but in the shape of a butterfly rash which is classic lupus .. I am going for the lesser of two evils.  I've had rosacea for many years but can't control it anymore with diet.  Now I've got whooping cough, I am infectious until 5 days of antibiotics and my appointment is in two days.  So will need to reschedule.  Mmmm this is not good I am feeling feverish as it is.
