About two months ago my son began complaining about a difficulty hearing in his left ears It went away for a while, then it returned. He says it's not so much a loss of hearing, it's more of a feeling of something in his ear, making things sound muffled. This is more in his left ear, though it occasionally happens in his right ear. His right ear usually just has a slight pain, which goes away quickly, which he has only experienced twice. That could be from the cold though.
With both ears he is able to hear fine. It usually feels like something is in his ear, so I thought something may be in it. He trys to blow whatever may be in there out by plugging his nose and trying to exhale, thus popping his ear drums, but it doesn't seem to work, and I told him to stop, even though it temporarily helps his hearing, although not fixing it.
I took him to the doctors and they cleaned out his left ear, but it hasn't helped him. He says the left one occasionally hurts, and he is very worried about it. He does listen to a louder type of music for a majority of his day, so that may be a cause. Please help me diagnose this.
