When you sit and get up, I hear your leg or knee making a sound. Why is it the solution?

The sound you hear when you sit or get up is likely due to the movement of the joints in your leg or knee. This sound, often referred to as crepitus, can be caused by a variety of factors including air bubbles in the joint fluid, rough or uneven joint surfaces, or the movement of tendons or ligaments over bone. While it is generally not a cause for concern, if you are experiencing pain or swelling along with the noise, it is recommended to consult a healthcare professional for further evaluation and treatment. Stretching, strengthening exercises, and maintaining a healthy weight can also help alleviate joint noise and discomfort.
