Are my hearing problems due to auditory processing disorder?

Hello doctor,

I have had a chronic migraine for almost five months now; no medicines or treatments have worked, and I will be transferring to a hospital with more resources soon.

Over the past few years, I have noticed that I am having increasing trouble hearing. You could knock, walk into the room, and ask me something, and I would not know you are there. Alarms will go off in other rooms for more than ten minutes, and only after I become aware of them and actively try to hear them will I notice them at all. The bell in my high school has gone off, and I have not noticed it. If I listen to audio without subtitles, I cannot figure out what is being said.

I cannot understand phone calls, and often in conversation, if someone does not speak clearly and at a good volume, I will not be able to hear and understand what they are saying at all. I also have occasional pain in my inner ear and pressure that feels as though my ears are clogged, even if they are not.

The other day, my hearing was tested at an ENT, and they told me my hearing is perfect. They mentioned that auditory processing disorder (APD) was a possible explanation, but said that if so, there would not be anything to do. I have looked into APD, and it was described as almost auditory dyslexia, which does not sound like an accurate description of what I am dealing with.

It is hard to process what could be going on, given that my ears were tested to be in perfect health.

I would greatly appreciate any insight or advice you could give me.

Thank you.
