Hi, my mother sometimes feels pain on left side of the throat at almost a singular point when she eats any spicy food ..pain goes away with few minutes and is not persistent. While I saw a small red spot on her left tonsil I also noticed some lesion like blackish pigmentation on both side of her inner cheeks. What could these be and is there anything to be worried about apart from appartment fungal infection? Attaching bith photos of inner cheek and left tonsil. She doesn't eat tobbaco nor smoke nor drink.
