I woke up Wednesday morning at 4:20 in so much pain I had to get up and take pain medicine again. I called the dentist and he said that since it had only been 36 hours since my root canal it might still hurt because of the infection. He explained that the tooth was like a sliver in your finger. He took out the sliver but the infection takes time to go away. Hopefully it will get better soon. So far Wednesday, I have felt pretty okay!
