mellors you might want to try gargling with warm salt water for your abcess. lots and lots of salt. it feels and tastes really yuck when you do it but does take the pain out of it. my dentist tells me to do that for any mouth ulcers or whatever and it really helps. not sure how good it would be with an abcess that size but it couldnt hurt to try. i hope you get some help soon. take care of yourself!
