This morning, I was blowing my nose and i think i blew a little too hard, because i felt some mucus go into my ear. Now its stuffy in that ear and sound is harder to hear from that ear. It feels like one ear is under more pressure than the other. My question is: is this a serious problem that needs medical attention, or will it go away after time? Will this cause deafness? I am really scared right now i cant get the ear to be normal again. what can i do?
