Alternate diagnosis?: UTI that spreads to the kidney causes flank pain, but rarely on both sides. Sometimes pain occurs on the opposite side due to muscle strain (caused by favoring the side that is originally in pain). A concern, especially if a pelvic exam was not done to rule this out, is pelvic inflammatory disease. Another concern would be kidney stones on both sides (also rare, but infection harder to treat)
