Kidney stone symptoms include waves of sudden, severe pain in the back, abdomen or groin. Often this is combined with nausea, vomiting, blood in the urine and painful urination, according to WebMD. If a kidney stone is very small, it may not produce any symptoms.
The location and sensation of pain caused by a kidney stone often changes as the stone passes through the urinary tract. Additional symptoms include cloudy, discolored or foul-smelling urine, a persistent need to urinate, scant urine, and fever and chills, notes Mayo Clinic. A patient with these symptoms should seek medical help if she's unable to sit comfortably due to severe pain, if she has trouble urinating or notices blood in the urine, or if the pain is accompanied by fever, chills or vomiting.
