Thank you all so much for your replies. It's very, very kind of you!!! The ENT this morning was not at all concerned, to the point where he didn't even recommend conducting a biopsy due to the soreness I'd have from it, etc. He believes (as I was hoping deep down) that it was irritation from my erupted wisdom tooth back there. I believed him and felt like he would not say these things if he wasn't absolutely sure. But I asked him to biopsy it anyway for my piece of mind and absolute certainty. He was very kind and willing to do so, even though it wasn't what he recommended. I'm glad I asked him to and I'll have the results on Monday.

I really can't thank you all enough for putting up with me.
