jackie2024, there is a flap in the back of the throat that you can touch called the uvula.

Bumps in the throat, called cobblestone throat, are a common reaction to allergies or viruses and usually resolve when you are over the virus and/or away from the virus. The swelling could be from either.
I'm more concerned about the loss or hearing. Though it may all be including the tinnitus from fluid from whatever is irritating your sinuses and ears.
I'd rather that you see an ENT, but medical care is expensive and your stepfather seems to have all of the power in your family. Is there a school nurse where you study?
