Renal colic is characterized by a sudden triggering of pain in one side of the abdomen or in the lumbar region, that appears and disappears and produces a pinching or burning sensation. The pain may be accompanied by sweating, nausea, vomiting, and sometimes urinary discomfort, like the feeling of wanting to urinate constantly or stinging and burning during urination.
Renal colic is a fairly common problem: in Spain four out of every hundred people suffer from this disease, which implies the apparition of approximately one hundred thousand new cases per year.
