The past few days I've noticed bumps on the back of my tongue... they were just visible if I stuck my tongue out far and didnt hurt or anything. But today, one of the bumps toward the left side just feels annoying. Like when a popcorn kernel gets stuck on the back of your tongue... thats what it feels like. I tried using a toothbrush to kind of 'brush' it away, and it didnt work. I've also had a white coating over my tongue and dry mouth for about 2 weeks, and the sensation of something being stuck on the right side of my throat. I have no clue what this could be... I have a doctor appointment, but not til Dec 12th.
