Oh, hon, that sounds absolutely awful. I'm so sorry you're having to go through this, and I hope they find out what's wrong very soon and figure out a way to fix it. And you're right--it does sound like an episode of House, except that the solution won't be found after a crazy doctor makes you confess that you've been lying about something all along. ;D
