Jan - good to know for future reference. I assumed that the cream treatments for athlete's foot would be too harsh for that region of the body.
ATXguy - You can get internal yeast overgrowth as well, so perhaps the oral antifungal is what you need. That being said, your current symptoms may be unrelated to the itch. You describe a broad range of symptoms that could be indicative of pouchitis, stricture, partial obstruction, or gastrointestinal illness (though since they came on suddenly, obstruction or virus would be my first guesses). If you were eating different foods for Thanksgiving, that might also be contributing.
Since you are away from home, if the symptoms persist, my advice would be to try to contact your GI or surgeon by phone or email if possible.
