As I said, Clogged ears have nothing to do with concussions. They can be connected to head movement causing ear wax to move and lodge in a way that makes the ear feel plugged.

Slamming a car door can cause an air pressure wave that can effect the ear.

You have to let go of these ideas of such minor events being a concussion. No concussion symptoms list includes clogged ears as a symptom of a concussion.
