I have an addendum for The Inferno. It is called dry socket. It can also be confused with biting down on a very very angry yellowjacket or being cracked in the jaw with a Louisville Slugger. Repeatedly. And it usually occurs no matter how carefully you follow post op instructions and on a weekend when the dentist's office is closed. And your dentist goes to church like a good little Christian man should which means he is unavailable for most of the day. (But, he still meets you at the office on Sunday afternoon anyway because he is a kind and merciful man, who happens to go to the same church as you.) However, in this place of torture, by nighttime, the other side of your mouth feels the same way when it is too late to call and bother the nice dentist man again, and another night must be endured till the office opens. Yes, you forgot one, Mr. Dante. I have been to this circle, and it is the worst of them all.
(and for the record, I am not just going for drama here, people-I birthed 3 babies completely epidural-free and have a pretty high tolerance for pain-this is different. Different in this instance=VERY VERY BAD)
