Symptoms

Cystitis signs and symptoms often include:

• A strong, persistent urge to urinate
• A burning sensation when urinating
• Passing frequent, small amounts of urine
• Blood in the urine (hematuria)
• Passing cloudy or strong-smelling urine
• Pelvic discomfort
• A feeling of pressure in the lower abdomen
• Low-grade fever

In young children, new episodes of accidental daytime wetting also may be a sign of a urinary tract infection (UTI). Nighttime bed-wetting on its own isn't likely to be associated with a UTI.

When to see a doctor

Seek immediate medical help if you have signs and symptoms common to a kidney infection, including:

• Back or side pain
• Fever and chills
• Nausea and vomiting

If you develop urgent, frequent or painful urination that lasts for several hours or longer or if you notice blood in your urine, call your doctor. If you've been diagnosed with a UTI in the past and you develop symptoms that mimic a previous UTI, call your doctor.

Also call your doctor if cystitis symptoms return after you've finished a course of antibiotics. You may need a different type of medication.

If your child starts having daytime wetting accidents, call your pediatrician.

In otherwise healthy men, cystitis is rare and should be investigated by your doctor.
