Kidney stones feel like very severe, sharp, and intense pain. This pain typically starts suddenly and is located in the back, side, or abdomen below the ribs. It can radiate to the lower stomach and groin area as the stone moves through the urinary tract. This type of pain is known as renal colic and is often described as one of the worst pains imaginable, sometimes compared to the pain of childbirth. The pain often comes in waves, fluctuating in intensity, and may last for minutes or hours. Patients usually feel restless and unable to find a comfortable position during these episodes. The sharp pain may start as a dull ache and then quickly escalate into a severe cramping pain as pressure builds from the stone blocking urine flow. Other sensations that can accompany kidney stones include:
- Burning sensation or pain during urination
- Frequent or urgent need to urinate, sometimes in small amounts
- Cloudy, foul-smelling, or blood-tinged urine
- Nausea and vomiting
- In some cases, fever and chills if an infection is present
Overall, kidney stones cause intense discomfort that often drives patients to seek emergency medical care due to the severe and relentless nature of the pain. The symptoms vary depending on the size and location of the stone but are generally characterized by sharp, cramping pain in the back or side, often moving toward the groin.
