My daughter has a frequent urge to urinate . It is keeping her up at night, she s loosing sleep. I need to try flushing her system with vitamin C rich juice and maybe use a different laundry detergent but I don t know if it is a symptom of a UTI or something else? So, just to be clear, she has the feeling of having to urinate constantly, even after she goes to the bathroom. Any ideas to help her?
