You don't have ear damage. You have done the same bs I have, which is hard / improper mewing, I read your introduction while looking for relevant threads here about mewing.
We messed your upper palate up and apparently now our jaw joints are too close to the ear. Muscle tension is definitely not helping and so is pushing tongue up the roof of the mouth if you're still doing it. One idea thrown at me was to reverse suction (which I won't do but you can try if you want): check the image posted.

Depending on how stupid each of us were, we could have ruined our bite significantly which translates to a thousand chew movements a day done wrong. But what we seem to have is a backwards bite. Sort of.
Leave your tongue be where it should be without pushing up or resting up, go to a good manual therapist to remove muscle tension from everywhere and then take X-rays from both your TMJ to see what kind of damage there is (hopefully reversible, as I don't think we are stupid enough to push enough to make the TMJ socket actually hit the zygomatic where the ear lies, or something like that). I want to believe it's just overworked and maybe slightly hypertrophic muscles in relation to the bad bite.
Orthotics can't reverse this as far as I know but perhaps they can, never say never. In other words, we are in deep sh*t but I think we can manage.
