I woke up this morning and it burned when I peed so I immediately knew I got a uti. I went to the dr and she prescribed me bactrim, told me if I feel better in 3 days I can stop taking it but if not I need to take the full 7 day dose (which I've never had a dr tell me to do that but whatever).

Anyways I took my first dose of bactrim 5 hours ago and I'm still in a TON of pain and the Azo makes me so nauseous. Is this normal? I looked up how long for antibiotics to start working and keep getting mixed answers.
