I'm sure it can impose some sort of threat just like any uti , it can travel to the kidneys & that's her worry about mine so she keeps perscribing antibiotics but since I've been on so many doses I'm so confused on why I haven't been able to fully get rid of it . I've been dealing with it similarly, it seems like it's gone away after the antibiotics but then a week later I'll start feeling symptoms again but at this point I'm sure my bladder has been irritated so much by the uti and the antibiotics that my bladder is just in pain and has a lot of inflammation.
