Shoulder clicking is a common experience. Many people notice a popping or clicking sound when lifting their arm, rotating the shoulder, or during exercise.
In most cases, shoulder clicking is harmless and caused by normal movement of tendons or joints. However, in some situations it can be linked to irritation or instability.
Common Causes of Shoulder Clicking
1. Tendon Movement
Tendons can move slightly over bone during shoulder movement, creating a clicking or snapping sensation.
2. Gas Bubbles in the Joint
Like cracking your knuckles, small gas bubbles in joint fluid can create popping sounds.
3. Muscle Imbalance
Weak or tight muscles around the shoulder blade can alter movement mechanics.
4. Labral Irritation
In some cases, irritation of the cartilage rim (labrum) may cause clicking along with discomfort.
When Should You Be Concerned?
Seek medical advice if shoulder clicking is accompanied by:
- Persistent pain
- Weakness
- Instability
- Loss of movement
- A history of injury
What You Can Try
Gentle mobility exercises
Strengthening the rotator cuff
Improving posture
Avoiding painful overhead movements
Summary
Most shoulder clicking is harmless and related to normal joint mechanics. However, persistent pain or instability should be assessed by a healthcare professional.
