Your daughter could have a kidney problem, which means she may be passing very little urine and won’t feel as though she needs to. If she is close to kidney failure she will make very little urine. I would seek an urgent Doctor’s appt.
She could have an urinary tract infection and may be putting off going if she is getting a burning sensation. A few years ago I had a UTI with no classic symptoms. It was diagnosed after persistent vomitting over a few hours, then a spike in temperature.
