Knee Pain: Causes, Symptoms, Treatment & Relief Options

What Is Knee Pain?

Knee pain refers to discomfort, stiffness, or swelling in or around the knee joint. It may affect one knee or both and can range from mild knee discomfort to severe pain that limits movement.

The knee is a weight-bearing joint, which means it takes a lot of stress every day. Walking, running, bending, and climbing stairs all put pressure on the knee joint, making it vulnerable to injury, wear and tear, and degeneration.
