I know utis are super common and everyone gets them sooner or later. Somehow I've managed to get into my thirties without ever having one until this week. Ouch!! I was on antibiotics for three days and it seemed to pretty much clear up but now it's back with a vengeance and the doc has given me another weeks worth of antibiotics. Is it usual for the infection to come and go like this? Any tips on how to deal with it?
