Manuka honey in hot water (with or without lemon) or propolis lozenges are what I used. Not sure where you're from but in NZ you get it at the supermarket or health stores. Manuka is much more potent than other varieties of honey but if you cacan't find it, then lemon honey and a teaspoon of apple cider vinegar.
Natural Apple cider vinegar is supposed to do wonders. Just read up on it and find the best way to take it.
I hope you feel better soon
Juice some Fruits and veggies too. Ask doc about a magic mouth wash. Or rather a mouth was with lidocaine in it. (Or some other type of "caine."
Unfortunately nothing:( try eating a spoonful of honey, drink lots of fluids/tea and double your vitamin C intake. Hope you feel better soon!
