Shoulder pain and popping when lifting your arm is often caused by snapping scapula syndrome, a condition where the shoulder blade rubs abnormally against the rib cage. Common causes include muscle imbalance, poor posture, overuse, or bone abnormalities. Treatment typically starts with rest, activity modification, and physical therapy to strengthen surrounding muscles. In persistent cases, corticosteroid injections or surgery may be recommended.
Because shoulder popping can also signal rotator cuff issues, bursitis, or joint instability, identifying the exact cause matters. Take a free, instant, online symptom check to better understand your symptoms and confidently plan your next steps.
