4. Having back pain
Kidney failure can cause back discomfort, often deep and placed just below the rib cage. It is most commonly felt at the front of the groin or hip region. Kidney cysts, which are huge fluid-filled sacs produced on the kidneys due to polycystic kidney disease, can cause back and leg pain.
Tip: Kidney failure causes back discomfort, nausea, vomiting, a high body temperature, and frequent urination. Regular back pain unrelated to the kidneys behaves differently: the pain is more localized and occurs abruptly, and there is no temperature. If your back discomfort persists and pain relievers are unsuccessful, arrange an appointment with your doctor.
