Can Sciatic Nerve Cause Knee Pain? Understanding the Connection and Treatment

September 1, 2025
Written By Admin

The relationship between sciatic nerve issues and knee pain is often misunderstood by many patients. While knee pain might seem localized, it can actually be a symptom of broader nerve-related problems originating in the lower back. Understanding this connection is crucial for accurate diagnosis and effective treatment.

Official Medical Perspectives

Medical sources consistently confirm that the sciatic nerve can indeed cause knee pain. The sciatic nerve runs from the lower back, down through the buttocks and legs, ultimately branching near the knee. When this nerve becomes compressed, irritated, or damaged, pain can manifest in various locations along its pathway, including the knee joint.
