When I pee I have the urge to go again and I think I have a uti but I don't know my mom says it's because I don't drink a lot of water?

Need a check-up... Many causes can incite urinary urgency other than UTI. How to unveil its possible causes? One needs to review more info on its onset, degree, duration, fluctuation, etc. + physical exam + properly testing as needed, which can be done by following instructions as described in http://formefirst.com/eNewsletter06.html; then you can work closely with doc so to reach diagnosis for right treatment.
