The kidneys are located against the lower abdomen's back muscles, so diseases affecting the kidney may present as a sharp lower back pain that occurs between the buttocks and the lowest rib, according to MedicineNet. Depending on the cause, this pain may be acute or chronic.
Lower back pain associated with kidney disorders normally affects one side of the body, but it may affect both sides or radiate to the groin or abdominal area, as stated by MedicineNet. Kidney stones and other conditions that slow or stop urine flow may cause a constant, sharp lower back pain known as renal colic, but individuals may also experience a dull ache with occasional episodes of piercing pain. This is due to cumulative damage caused by conditions such as diabetes and polycystic kidney disease.
Other conditions related to kidney pain include urinary tract infections, gomerulonephritis, kidney infections, high blood pressure and certain drugs that harm the kidneys, as confirmed by MedicineNet. Some conditions unrelated to the kidney that may cause similar symptoms include spinal problems, shingles and muscle strains. Individuals should seek medical attention for proper diagnosis as soon as they begin experiencing kidney pain. Additional kidney disease symptoms that may accompany pain include blood in the urine, high blood pressure, frequent urination, puffy eyes and swelling in the hands and feet.
