Hi doctor, 2 days ago my throat was hurting, had difficulty swallowing and my tonsils were swollen and red, there was no white patches, just the back of my throat and sides by my tonsils inflamed. the next day after i was having a runny nose with yellow discharge in the morning with thick consistency and later on the same day turned clear with yellow tinged and more thin in consistency. My lung sounds were clear. I have a dry cough occasionally and i started to notice this yellowing on my soft palate on the sides near my tonsils. What could this be? should i be worried or just let it run its course?
