I had sore throat and bad cough for a month but cough is gone now but i still feel like coughing sometimes and throat feels scratchy because of post nasal drip. There is some white mass near one tonsil and there is a white layer kind of thing in almost whole mouth. Yesterday i had some inflammation inside lower lip. I have attached all the pictures of throat and inner lip. There is also one mole size spot on right cheek with no pain. Please tell me what is it.
