Why do I get the feeling that the OP will spend a few weeks sucking up to his daughter, then slowly revert back to not believing her when she doesn't get better? Either way, OP is lucky that his daughter wasn't suicidal (or, I would hope not), otherwise he'd likely be short a daughter (which he hopefully isn't) because trigeminal neuralgia has a very high suicide rate, especially in locations with excessively strict regulations on pain medication. Scrape and bow, OP- or do something that says that you believe her, like getting her one of those ice/heat packs that you wear on your head.

asshole is too good of a word for you.
