It is probably food that has got wedged deep into your tonsil. You may be able to gently push and remove it. I ended up seeing a specialist who did prescribe strong antibiotics as he said that I had a throat infection and that the lump was nothing sinister. Although I continued to worry and look at it, I convinced myself that all is okay and just left it alone and eventually the sensation of it being there went away. You might just need antibiotics because the red ring you describe sounds like you have an infection of some sort. Good luck.
I have the same issue as you. I just started to notice it a couple days ago and thought there was something stuck in my throat. I can feel it with my finger and it feels hard and when I look at it with a flashlight, it looks white with a red ring around it. When I swallow, it feels like something sharp is there. I don't have insurance and don't even have a job so I'm gonna have to wait and see if it gets worse before I even go to the hospital. And ideas on how to figure out what it is?
Thanks for help, but I always thought that tonsil stones came out with a bit of prodding.
It could be a tonsil stone, only I'm not sure about the blood blister part. I know I've had sores in my mouth that look like blood blisters from sharp food like pretzles poking it. So I guess that could be from you poking it. But I'd continue the antibiotics, and wait and see if the blood blister part goes away. If so, consider tonsil stones, also known as tonsiliths.
