The symptoms of a bladder infection include a painful sensation while urinating, bloody or cloudy urine, a frequent urge to urinate, and pressure in the lower back or abdomen, explains Healthline. Patients may also produce foul-smelling urine and have a low fever.
The most common symptom of a bladder infection is a burning sensation when passing urine, explains WebMD. Patients may experience a frequent urge to urinate. However, they may pass small amounts of urine despite this urge to urinate. They may also feel the need to urinate at night, reports Drugs.com.
Bacteria in the bladder can cause pus that clouds the urine, reports MedicineNet. The bladder may bleed, causing traces of blood in the urine. The urine may have an unusually strong and unpleasant smell. Bedwetting in children who do not normally wet their beds is another symptom of a bladder infection. Children who have bladder infections may appear fussy and lethargic.
Bladder infections also commonly cause pain in the abdomen, notes MedicineNet. Men may have pain around the rectum, and women may experience pain around the pubic bone. Patients with complicated bladder infections often have additional symptoms, such as chills, fevers and nausea, explains Drugs.com. They may have flank pain, back pain and confusion. These symptoms often indicate that the bacteria have spread to the blood or the kidneys.
