What should you know about shoulder rotator cuff clicking?

A tendon can move over bone as the arm rises, or a small pressure change in the joint can create a pop. Clicking becomes more meaningful when it began after an injury, occurs with pain, or is paired with reduced strength. Shoulder instability can produce a slipping or shifting sensation, while shoulder osteoarthritis may cause grinding and stiffness. The sound alone cannot identify the cause.

Reduce movements that repeatedly provoke the click for a short period, but keep the shoulder gently moving within a comfortable range. Avoid testing it with heavy lifting. Note whether the sound occurs during reaching overhead, rotating the arm, or lowering it, and whether swelling, weakness, or night pain is present. A clinician or physiotherapist can check shoulder motion, strength, and control before suggesting targeted exercises.

Arrange an assessment if clicking persists with pain, limits daily tasks, follows a fall, or comes with weakness or repeated slipping. Seek urgent care after a major injury if the shoulder looks deformed, the arm cannot be moved, or the hand becomes numb, pale, or unusually cold.

Could the sound be coming from a tendon, the joint surface, or instability? Which movements should I pause, and which should I continue? Do I need a strength and range-of-motion assessment or imaging?
