Joint Clicking May Signal Underlying Disease, Doctors Warn

Clicking and popping sounds from joints, such as knees and shoulders, are a frequent experience for many people. While often attributed to simple friction between cartilage and tendons as joints move, these noises are not always benign. Medical experts caution that when these sounds occur alongside pain, swelling, or restricted motion, they could indicate a more serious underlying joint condition. The shoulder joint, with its wide range of motion, involves numerous structures interacting, which can produce temporary friction sounds. These everyday joint noises are usually not a cause for concern. However, if a clicking sensation accompanies pain when raising the arm, or if pain recurs at specific angles, it may point to shoulder impingement syndrome. Dr. Kim Joong-hyuk of Nanuri Hospital's Joint Center explains that this condition arises from the repetitive compression of shoulder tendons under the acromion, leading to inflammation. Left untreated, it can progress to rotator cuff damage. He specifically notes that persistent night pain and difficulty lifting the arm are significant symptoms.
