An uncontrollable desire to urinate. In a bladder infection, the bladder becomes extremely constricted and can hold only a minimal amount of urine. This puts pressure on the bladder, making the urge to urinate uncontrollably. While a healthy person may be able to resist this urge for a small period (not that this is a good thing to do), a person suffering from an infection of the bladder finds that they must go at once. Another indicator of a bladder infection is passing only minute quantities of urine and feeling the urge again almost immediately.
A feeling of discomfort around the pelvic region. Your hips form a bowl-shaped bone called the pelvis. This bowl of bone contains tissues and organs that are part of, or at least in contact with, your body’s urinary system. If the urinary tract (and this includes the bladder, connecting tubes, and the kidneys themselves) is inflamed, the pelvic bone itself and the connecting muscles will experience considerable distress. As the infection advances, tissues will become inflamed, and the swelling will put pressure on the pelvic bone itself. While this distress and discomfort are mild, it is still extremely noticeable whether you are sitting or standing upright.
Discolored urine. If the urine passed is discolored to a considerable extent, or if it has a strange smell, these are clear indications of an infection of the bladder. The urine may be very dark, or it may look clouded. It can also have a bloody tinge to it, which can be quite disturbing to a patient. Generally speaking, this will also be accompanied by a bad smell. If one is experiencing any of the other symptoms of a bladder infection, it is good to check on the color of the urine, as this is one of the clearest indications of a bladder infection.
