For a patient who is experiencing kidney stones for the first time, it can be difficult to know when it is time to see a doctor. An increase in urination, burning sensation during urination, or urine that is red or dark in color are all signs that you should see a doctor. Nausea and vomiting, as well as an intense need to urinate can also indicate that kidney stones may be the culprit. One of the most common indicators that you may be experiencing kidney stones is an intense cramping pain in your side and back that can move into the groin or lower abdomen. This pain is the result of your body attempting to pass a kidney stone and can begin very suddenly, coming and going in waves.
