As kidneys lie close to your back muscles, the ache can feel similar to back pain, but differs in location, severity, causes, and treatment. Being well-informed about these parameters is important for accurate and timely medical care. So, keep reading to discover the exact location of your pain along with the symptoms, causes, diagnoses, and treatment approaches.
