My daughter just got over a uti and have finished her antibiotics. today she's complaining about stomach ache and her urine is a fluorescent yellow.

UTI: Usually you have 2/3 symptoms to diagnose a UTI, dysuria or burning, peeing often or feeling like you need to pee often. A positive urine culture is helpful. Abdominal pain is not specific and can represent something else. The bright yellow urine is related to something she ingested, maybe the antibiotics. Have her checked, sounds like a new problem. All the best.
