The sides of my throat is very red and now my tongue is white. I have no pain but I don't understand why they are red and why my tongue is white?

White tongue. On any form of steroids?, inhaled steroids for asthma? Have an autoimmune disease on medication?immunosupressed? diabetes? These can predispose to thrush which is a fungal infection in the mouth (yeast) and is treated by dilfucan or nystatin trouches. The thrush can cause irritation and redness elsewhere in the mouth. Could also be strep . Follow up w/doc/ urgent care today.
