A high count of red blood cells in the urine can indicate infection, trauma, tumors, or
kidney stones. It is likely to be an infection as it's associated with fever. I would advise you to visit a urologist so that you can be examined and undergo the necessary investigations to find the underlying cause and have it treated accordingly. If the problem persists or worsens visit the ER at the earliest.
