Abscess tooth makes it easy to diet...

I realize that not eating is the worst way to lose weight but right now I don't have a choice. My tooth hurts so bad that the whole side of my face hurts from my neck to my temple and everything in between. The pain is unrelenting and I feel like it will go on forever. Supposedly the painkiller they gave me should help but it doesn't seem to do anything. The constant pain and medication have made me lose my appetite and even when I force myself to eat something, it makes the pain worse which then makes me less inclined to eat. So far today I've had an orange and 1/4 cup of tomato soup. Yesterday, I had a small piece of flounder and a few bites of asparagus risotto. I am desperately trying to take my mind off the pain by writing this blog. The dentist said the antibiotics should take effect within 72 hours. I started taking them yesterday at Noon so I'm not even halfway to that point. I just keep telling myself that this is only temporary and surely the pain will stop eventually. I am praying for it to stop. I guess on the bright side I will probably lose a bit of weight from my unintentional fasting but it's a high price to pay. Anyone have an abscess tooth where the pain won't stop? What do you do? I've tried heat and cold but neither helped. Sorry to be such a whiner. I've had abscesses before but this one takes the cake.
