What are symptoms of passing a kidney stone?

Flank pain: Usually flank pain on one side, blood in the urine, and occasionally some nausea and difficulty peeing. People who have never had a kidney stone should get checked out by their doctor to make sure the diagnosis is correct. People who have these regularly usually recognize them and know what to do. Anyone with fevers, extreme pain, or symptoms that last longer than a day or two should see a doc.

Pain!: The most common symptoms associated with kidney stones are renal colic, or spastic pain which usually radiates from the back down to the groin, blood in the urine, and nausea and/or vomiting. If the stone is down by the bladder, you may also experience pain at the tip of the penis (in makes) or at the urethral opening (in females), as well as a constant urge to urinate. See your urologist.
