It may be way to late but hopefully you can see this and let me know how you are. The same thing has been happening to be for the past couple of years. It seems to get better in the winter and once spring comes around, it gets bad.
The closest someone has been able to explain to me was one ear nose mouth doctor. She says it’s some type of crusting on a node (I can’t remember which one) due to antihistamines or something like that. I’m going to look more into it because it is seemingly getting worse for me.
I hope that you’re better.
