Since : Since i see that you asked this question a few days ago, i hope your problems have resolved! for future reference, if you are having pain that is so severe that you cannot wait for a scheduled test or appointment, then give your doctor a call. They may want to see you sooner in the office or may instruct you to go to the emergency room.
