The back of my mouth and roof of mouth are yellow with red patches. It's been painful to swallow hard food for the past month and half, I told my primary and she was unsure where the pain was going from. Now I have pain throughout my throat, painful to swallow, and yellow roof of mouth and back w/ red dots sprinkled throughout the yellow. My tongue is normal no yellow on it or any other color issues. Should I go see Ear,Nose,and throat Doctor? What could this be?
