I Received Metronidazole 500mg And Cirofloxacin 500mg From A Doctor

I received metronidazole 500mg and cirofloxacin 500mg from a doctor yesterday. And I started taking them yesterday and the burning while peeing slow down a lot like it's trying to get better so I'm still taking the pills she told me take them for the next week and it should get rid of it but today I used the bathroom and it's burning again so I need to wait a little longer for the burning and hurting to stop?
