Eric here again, with some good news: Anne is no longer in pain!
I will keep this brief but just wanted everyone to know that she is in no pain at the moment. Our doctor was concerned enough with how much pain she seemed to be in to get a consult from a chief surgeon, and ultimately asked him to do a procedure which essentially consisted of inserting a tube you-know-where in order to let some gas escape. He did this and the effect was immediate: Anne went from intense, constant pain to immediate relief faster than you can say fart. Another doctor has since commented that it was like seeing two completely different patients before and after the procedure, and I can attest to that. Two hours ago she was in a rather uncommunicative morphine fog and now she's perky, happy, and beating me at Quiddler.
(Incidentally, Anne had been requesting a procedure of this type since Saturday night.)
Life is good again - just wanted to share this great news!
