@deedubs-sometimes the musculature in that area can give off a feeling of ear fullness. The sternocliedomastoid (SCM) muscle into the mastoid process bone, as well as jaw muscles can all cause this feeling and is often overlooked. If you press directly behind your ear, sometimes you can even feel some soreness or trigger points. They don’t know why this also can cause a feeling of hearing loss as well. If like you say, your whole right side is a mess, it might be worth checking the musculature in that area. Tight/tense/stressed muscles can cause all kinds of congestion. And I don’t mean congestion in your nose I mean congestion like a traffic jam.
