Yes, I have those issues. Clogged ears are a normal way to feel after an upper respiratory infection. I also get that feeling during allergy season. I suggest that he can't see congestion in the inner parts of your ear. The only way to see that is with an MRI or CT scan and those are expensive. Without more serious hearing loss or symptoms your insurance won't pay for it.
And, I wear hearing aids. The process of getting hearing aids was one of having my ears tested more than once over several years. At first, I didn't need aids. At the next, they would possibly be helpful. At the last, yes, I needed them.
Hearing loss is also natural. I suggest that having a mild hearing loss at 29 is normal. Talk with the doctor about this. You could wait until your ears feel clear and test again. However, I suggest that this is nothing to be concerned about. It's normal.
You had several conditions that would affect your ears. I suggest it's just a matter of waiting it out as your ears heal.
