Uti or?

Allison

So the dr prescribed antibiotics on thursday morning and started it thursday night. Now its sunday night. Thursday I felt pretty bad but now i have low back pain and feel like i need to pee a little all the time. Has the antibiotic not had enough time to work? She prescribed some azo stuff thats a prescription but i haven't taking it so i can tell if the antibiotic is working our not. Its just to help the symptoms not treat the infection.
