The helpful nurse side of me wants to offer help :(
You can try to rinse your mouth with warm sea salt water. Enough to make it taste like tears. It helped my lip piercing which was very raw and sore with a stud and is helping heal it fast now that I have a ring.
As for the ear wax; my son is going through that now. Pediatrician said to use 1/2 warm water to 1/2 hydrogen peroxide. I use a medicine syringe to drop it in but a cotton ball or Q-tip can work too. Leave it in a bit and put a cotton ball in to catch the crap that comes out. Works like a charm and cheap.
Hope you guys feel better!
Edit: For ear wax, you can try this if you're ballsy. It's using a candle...
