Chapter 2: The Symptoms You Should Pay Attention To
One of the most recognizable symptoms of a kidney stone is sudden, intense pain. Unlike ordinary muscle soreness, renal colic can be extremely severe and may change location as the stone travels through the urinary tract.
Pain may occur in the back, side, lower abdomen, or groin. Some people experience pain that comes and goes in waves rather than remaining constant.
Urinary symptoms can also occur. A person may feel an increased need to urinate, experience discomfort while urinating, or notice that the urine appears pink, red, or brown because of blood.
Nausea and vomiting are also possible, particularly when the pain is severe.
However, symptoms can vary considerably from person to person. Some individuals may have relatively mild symptoms, while others experience pain severe enough to require emergency medical treatment.
One of the most important warning signs is fever or chills in combination with suspected kidney stones. A blocked urinary tract together with an infection can become a serious medical emergency. In this situation, prompt medical attention is particularly important.
Cloudy or foul-smelling urine may also indicate a urinary infection, although these symptoms can have other causes.
People should not attempt to diagnose the size or location of a kidney stone based solely on pain intensity. A very painful episode does not necessarily tell you how large the stone is, and relatively small stones can sometimes produce tremendous discomfort.
If severe pain develops suddenly, especially when accompanied by vomiting, fever, difficulty urinating, blood in the urine, or worsening symptoms, professional medical evaluation is the safest choice.
Kidney stones can sometimes pass naturally, but the decision to wait should depend on the individual's symptoms and medical circumstances—not simply on whether the pain temporarily improves.
