Blood in Urine
In some advanced cases when the infection progresses and damages the tissues in your bladder, it would lead to blood in the urine. This is a very serious symptom that requires immediate medical attention. Otherwise, the bacteria would attack further and spread to other areas in the urinary tract. However, it is not always easy to notice the presence of blood. Sometimes, these blood cells can be too small to spot. Therefore, your doctor might have to take some special tests to know. [5]
