Chris,
By now you are out of surgery and I hope everything went well. I had the same surgery and a neck dissection thrown in for good measure. I was amazed at how pain-free the whole process was. I was walking with my daughter 5 hours after surgery. I could talk well enough to be understood and most of my discomfort was in my throat from the neck node surgery. They have come a long way in controlling pain. Having my wisdom teeth removed 30 years ago was more painful. Any how, I hope you are resting comfortably and experience a quick recovery.
