For several months now my right ear has been clogged up.
Resulting in hearing loss and frequent popping like I'm on an
airplane. I've tried solutions, drops, ear candling. I've been to
doctors who can't find a thing wrong. Does anyone have any
suggestions on what to try next? Thank you.

You could try a few drops of hydrogen peroxide on a q-tip.

That's usually what I do for clogged ears. works for me.
