Patient's question:
It is said that polycystic kidney disease, apart from being prone to causing high blood pressure, can also lead to many discomforts in the body. Lately, I've been experiencing severe lower back pain. The condition of polycystic kidney disease has been fluctuating again and again. Do you want to know about the lower back pain caused by polycystic kidney disease?Doctor's answer:
Lower back pain is the most common early symptom of polycystic kidney disease. The pain can be caused by urinary tract infections and kidney stone colic due to cyst expansion, and in very rare cases, renal cell tumors may also occur simultaneously. Mild pain may cause abdominal pain and discomfort, while severe pain may cause intense pain. The pain includes abdominal pain, rectus muscle pain, groin and thigh pain, or pain caused by diaphragmatic irritation, which is usually relieved by activity. The severity of the pain varies greatly, and the exact mechanism is still unclear. It may be caused by cyst expansion and stretching of the renal capsule, compression of renal parenchyma, or traction on the renal hilum. Persistent worsening or natural fluctuations in pain may indicate complications, such as kidney stones, kidney bleeding, hematomas, intestinal obstruction, infection, or malignant tumors.
