"Doctor, I can't talk"

I'm suffering from a bad case of wisdom tooth swelling, heatiness - is there such a word? - and ulcer all at the same time, same area in the left side of my mouth. I can't even talk properly now. *BIG SIGH* Had to drink 2 packets of soup just now coz I couldn't open my mouth to eat. Anyway, below is an extract from an email between Airen and myself. I was whining and desperately trying to get an mc.

The thing is, how to tell the doctor I cannot open my mouth to talk when I erm...can't open my mouth to talk?
