Kidney Stone Symptoms

Introduction

Kidney stones are a common yet painful condition affecting people of all ages. Recognizing kidney stone symptoms early can help you seek timely treatment and prevent complications. These stones form when minerals and salts build up in the kidneys and crystallize.

What are kidney stones?

Kidney stones are hard deposits made of minerals like calcium, oxalate, and uric acid that form inside the kidneys. They can vary in size—from tiny grains to larger stones—and may travel through the urinary tract.

Common kidney stone symptoms

1. Severe pain (renal colic) — Intense pain in the lower back or side; may spread to the lower abdomen and groin and come in waves.

2. Pain during urination — Burning or discomfort while urinating when the stone moves through the urinary tract.

3. Frequent urge to urinate — Needing to urinate more often, even if only a small amount passes.

4. Blood in urine (hematuria) — Urine may appear pink, red, or brown.

5. Cloudy or foul-smelling urine — May indicate infection along with stones.

6. Nausea and vomiting — Stomach upset due to shared nerve pathways.

7. Fever and chills — May signal a serious infection; seek care immediately.
