It should start working within 24-48 hours and you should start feeling better, but you do have to continue the therapy for 10 days.
I have had several UTIs and have found the over- the -counter pain meds for such ( the ones that turn your urine bright yellow) to be very helpful while the antibiotic was taking effect. You should still make sure you take the full course of antibiotics, however.
thanks for that, the antibiotics werent working so he told me to stop taking them. shame im still in pain though
