Abscessed tooth

My number 18 is abscessed. I've been in some pretty rotten pain since Friday. I went to see my wonderful dentist this morning and she says I need a root canal and a crown.

She referred me to an endodontist but I can't get in until next Tuesday so I have to take some pretty weird antibiotics (take every six hours with 8 ounces of water and don't lay down for half an hour after you take it) and some painkillers until I can get the root canal. I dread the next few weeks of my existence.
