It's so painful...

I went for my 2nd treatment of the root canal process. The dentist put in three screws into the molar. There was so much drilling in the tooth and I had to open my mouth wide so that he can see and put in the screws. My jaw was so tired.

The last appointment would be in March. Not sure why this time the root canal treatment causes me so much pain. It hurts so much after the anesthesia had gone off that I just feel like crying. Painkiller doesn't seem to relieve much pain either. I guess I'd just take 2 painkillers and sleep early tonight. :(
