Unrelated but I also gave up on fixing my problem: For the past ~8 years I have a constant feeling that one of my nostrils is almost closed and hard to breath. I went to several doctors, did all kinds of exams and they found nothing.

I feel like I need to blow my nose all the time and it drives me crazy sometimes. It gets worse when I have a flu. Sometimes it even bleeds a little, like it's irritated.

My family thinks I'm crazy so I stopped mentioning a long time ago, and one of the doctors even laughed at me.
