Acute pain is pain that is directly tied to tissue damage — a sprain, strain, fracture, tear, or other injury. It is the body's natural alarm system, signaling that something has been damaged and needs attention. Acute pain is typically sharp and well-localized, meaning you can usually point to exactly where it hurts. It tends to be at its worst in the first 24 to 72 hours and begins to improve as the initial inflammation subsides.

Knee pain in runners can stem from various factors, with overuse emerging as a primary culprit. Pushing your limits is commendable, but exceeding your body's recovery capacity can lead to inflammation and pain in the knee joint.

However, understanding its causes and implementing proper preventative measures, can help you manage and even prevent runner's knee, letting you enjoy your runs pain-free.
