A couple of months back i had 4 circular structures at the back of my tongue. Now i have 6-7 of them. These don't cause any irritation or pain. I feel that the food containing spices seems too spicy to me. I don't know if it is related in any way. These structures are light pink in colour and are slightly elevated. Lately, i saw 2 of them near the beginning of my throat (these 2 are not on the tongue). What problem could it be?
