Bladder Infection
Introduction
Cystitis is infection of the bladder. Usually, bacteria are the cause of cystitis. A frequent need to urinate and pain or burning while urinating are the most common symptoms. Doctors can often base the diagnosis on the symptoms, but they usually examine a urine specimen. Medications are needed to treat the infection and often the symptoms.
