Hi, I went with a plain abroad and felt terribly: Pressure in the ears, runny nose, painful respiration, ... I don't think I had a cold beforehand. The pressure in the ears and the runny nose disappeared after a couple of hours. But the painful respiration stays. Even if I breath through my nose, a part of my upperchest (I think the region of my larynx) hurts. I feel also that the pain increases with activities (singing, walking, drinking, ...) and by bending forward. Greetings from Belgium.
