The first sign of a bladder infection is often a strong urge to urinate that cannot be delayed. Very little urine is eliminated, and the urine may be tinged with blood. Soreness may occur in the lower abdomen, in the back, or in the sides. Symptoms associated with a urinary tract infection, such as painful urination, can be caused by other problems such as an infection of the vagina or vulva. A diagnosis can be made by testing a urine sample.
Treatment usually involves antibiotics and plenty of fluids.
Any symptoms of infection should be examined immediately. Urinary tract infections tend to recur in some people and, if left untreated, can cause permanent kidney damage.
