pain comes
in waves and fluctuates
in intensity, and may be associated with nausea, vomiting, fever, and chills if an infection is present. Other common symptoms include pain during urination, persistent urge to urinate, and frequent urination. You may also notice pink, red, brown, or cloudy and foul-smelling urine.
