Kidney stones: Hidden symptoms & how to know if you have passed a stone

Kidney stones can cause severe pain. The symptoms vary depending on their size, location, and whether they obstruct urine flow. Kidney stones are a risk factor for other systemic diseases such as diabetes, cardiovascular disease, bone fractures, and chronic kidney disease.
In case of small kidney stones, you may not necessarily notice any symptoms. Such small stones usually pass through urine while urination, without any discomfort. However, large stones can cause many symptoms, which range from mild to severe.
