My daughter (15) starting having 104 fevers the day before Thanksgiving. Took her to the Dr and it was determined she had flu. 4 days later she is still not better, Dr admitted her for severe dehydration. Fever still had not subsided 3 days later, every test under the sun came back negative, so they started her on a Flagyl and fevers stopped!! We never would have guessed it was pouchitis from the beginning! She's on a Flagyl for 14 days...fingers crossed it completely goes away!
