So I saw my dentist this morning for an on-the-spot root canal. It turned out that it was much worse in there than he thought from my description and that had I not gotten my UTI and started antibiotics Saturday it might have made me pretty sick by now. He must have told me 7 times that my pain tolerance was very high. At one point (don't read if squeamish) he was cleaning up in the tooth and it was so irritated that the numbing was ineffective, so he was flushing it was lidocaine as he went and still not getting all the pain.
He is very good about my bipolar issues and understands well because his brother is bipolar. He told me at the end that he wonders if the two issues make for the increased pain tolerance.
It's an interesting thought.
And now, back to my vicodin-induced coma.
