I remember one time when my brother had problems with ears and i said to him that i can't believe that you have such problems because i haven't had any problems whatsoever during many many flights. Well, few days later we boarded Air Asia flight somewhere in Asia and it started. First there were pressure on my ears and slowly i couldn't hear a thing and said to my brother that this new to me and he was repeating my words "i never have problems with my ears". I wasn't amused because it was getting worse, soon my whole right side of face, especially my forehead was in pain and i was afraid that im having somekind of brain-stroke After we landed i had strange feeling in my ears for many days. Im sure that there was somekind of problem with pressurization or something, we were seated in the two first rows and i haven't had any problems with my ears exept that particular flight.
