• Pain is the primary symptom
  Severe pain in the side of the back that may move to the groin
  Abdominal pain
• Nausea and vomiting
• Bloody and/or cloudy urine
• Frequent urge to urinate
• Fever and chills (when infection is present)

Symptoms vary depending on the size and location. Stones too large to pass may completely or partially obstruct the urinary tract causing sharp pain. Other symptoms of stones can be frequent urination, blood in the urine, a burning sensation during urination and possible infection accompanied by fever, vomiting, nausea, loss of appetite, and chills. If the stone is too large to pass easily, the severe, constant pain continues as the muscles in the walls of the tiny ureter try to squeeze the stone along into the bladder. Sometimes the individual will find blood in the urine, and may experience a burning sensation during urination, or increased frequency of urination.

Kidney stone pain often begins suddenly when a stone moves from the kidney into the ureter, causing irritation or obstruction. Individuals may experiences pain in the back and side in the vicinity of the kidney or in the lower abdomen. Later, the pain may radiate to the groin when the stone is moving toward the bladder.
