I have a 13 yr old daughter who since she was small had dark strong smelling urine and constant symptoms of either uti or kidney infections only to be tested to find no actual infection except on the rare occasion. She seems to go through boughts of this where she has painful burning when urinating, going often in small amounts, dark urine, strong smelling, lower back pain, leg pain, discharge. We have gone through thinking it must be a bladder infection, kidney infection, even down to thinking she wasn't wiping as she should and causing irritation. We are at our wits end and are yet again set out to go to the ER and I am not leaving this time until they can tell us something! Anyone have any info, similar situation, advice????
