You may not notice any symptoms if you have microscopic hematuria. If you have gross hematuria, you may notice that your urine is pink, red or brown. This happens because the blood in your urine makes it a different color. If you have gross hematuria, you may also get blood clots in your urine, which can be painful.
If you notice that your urine is a different color than normal or if you are having pain when you urinate, tell your health care provider. He or she can do some tests to figure out why you have blood in your urine or what is causing the pain and what treatment would be best for you.
