It felt like a popcorn husk stuck on
the back of my tongue
and when I looked I found the bumps
. Just like you, a couple on one side and about twice as many on the other. No pain, they don't look ulcerated, just bumps. Also, like you, when I researched on the internet, it just scares you what you find. I'd love to hear what you found out about your's and if they have cleared up.
