Hi, I just received a phone call from my father telling me that he has has had a sharp pain in his ear for a few days, he also had some bleeding after he stuck a q-tip down his ear (I advised him not to do that). He is also experiencing ringing in his ear. He is also telling me that he cannot hear very well in this ear, he says that it sounds hollowed out, and I must add that he has experienced problems with this ear in the past. What do you think it could be?
