what causes ruq pain
Diseases that cause inflammation of the right kidney may lead to RUQ pain. Kidney and urinary tract infections can be associated with abdominal pain, back pain, and burning with urination. Kidney stones can irritate the urinary tract or block urine flow from the kidneys.
But, when the pain is localized to a specific region of the abdomen, recurs or does not go away, or is severe, there may be underlying causes that require medical attention. Causes of right upper quadrant abdominal pain may be due to something as simple as increased stomach acid or involve infection or organ damage.
Liver problems often cause right upper quadrant abdominal pain. The liver helps remove toxins from the blood and when the liver becomes infected or diseased, abdominal pain is often the first symptom. An infection may also cause abdominal swelling and jaundice (yellow or sallow colored eyes and skin).
