I hear you.

Personally I'd take some Motrin if that brings the pain level down. If you don't want to keep taking that, then try something that's not NSAID. If I was in that much pain I'd probably ask the pharmacist for Panadeine (with the codeine), but that's just me. Having pain in the mouth/ear like that is just awful.
I can't help with your other questions but just wanted to post to say that I read it and that I'm sorry you're still in so much pain. I really hope that settles now that the sutures are out.

take care there.
