Scared about bumps at the back of throat

Hello everyone!

I've noticed approximately a month ago that the very back of my throat (plus esophagus) is full of small little bumps like raindrops / blisters in random places all around. Now I'm terrified I have some kind of oral cancer. Is there anyone who is struggling with similar symptoms or could tell me what it possibly could be? I've read about cobblestone throat, pharyngitis, but it did not ease my mind. I don't have a sore throat, maybe a really mild one, but I might have some difficutly swallowing /incomplete swallowing (that could be my imagination though).

I don't want to go to the doctor unless absolutely necessary, as there might be a second wave of covid on its way.

Oh, and I'm a 24 years old female if that matters.

Thank you in advance!
