Did you ever see the allergist? I saw in another post if yours that your biopsy result said hyperplasia just like mine did. Your lymph tissue is reacting to an irritant.

Edit: also wanted to ask you if your ct scan said anything about your sinuses being swollen. I have noticed that my bot problem flares up when my right nostril is clogged which is often. Supposedly I have a deviated septum and that can cause sinus issues. Everything in there is connected. Also when the doc biopsies my spot my nose and ear unclogged immediately for a awhile.
