Like me, when I breathe, one nostril is stuffed. When I breathe, I often feel reverberation in the same ear. I went to the hospital to see a doctor. As a result, the doctor said that I had rhinitis (caused by wiping my nose when I caught a cold a long time ago), which blocked the passage between my nose and my ears. Generally, we should pay attention to try not to catch a cold and prescribe some anti-inflammatory drugs. It is best to treat rhinitis, which is generally no problem.
