Why Do My Joints Crack and Pop During Exercise?

You may have noticed sounds coming from your knee, shoulder, or other joints during exercise. These sounds, regardless of their type or cause, are known as crepitus, and they often lead to concern.

Crepitus can be classified as either physiological or pathological. Physiological crepitus is quite common, especially in the knee joint. Pathological crepitus is usually accompanied by pain and may result from injury or trauma. In contrast, physiological crepitus is often caused by changes in joint pressure that lead to the formation or bursting of tiny gas bubbles in the synovial fluid.

So, if you hear joint sounds during exercise without any pain, there is usually no need for concern. However, if those sounds are accompanied by pain, it’s important to consult a doctor.
