Kayley has all of the symptoms of a urinary tract infection over a holiday weekend. She recalls that in the past, the urinary analgesic, phenazopyridine, has relieved her symptoms very quickly, so she asks a friend to pick some up for her rather than braving a crowded health clinic. As before, Kayley gets rapid relief of her symptoms. Should Kayley be concerned about anything else?
 A) Yes. Phenazopyridine treats the symptoms, but will not cure the infection, so she still needs to see her doctor.
  B) Possibly. If the infection was caused by bacteria, she will be fine, but if it was caused by a virus, she will need to see her doctor.
  C) No. If the phenazopyridine has alleviated the symptoms, she should be just fine.
  D) Possibly. If she experiences a return of symptoms after taking the phenazopyridine for a week, she should see her doctor.
