What is shoulder impingement syndrome?
It occurs when shoulder tissues (often the rotator cuff tendon) become compressed (“pinched”) either externally under the acromion or internally when the ball of the shoulder joint presses against the socket during abnormal motion.
What are the typical symptoms of impingement?
Pain radiating down the arm a few inches below the shoulder, pain at the front, side, or back of the shoulder, and discomfort aggravated by raising the arms overhead or reaching behind or across the body.
What causes shoulder impingement?
Repetitive overhead shoulder motions (from sports or work), mechanical changes in shoulder movement, or anatomical variations in shoulder bones. Overuse and repeated motion are common contributing factors.
How is impingement syndrome treated?
Conservative options come first: rest, physical therapy, and possibly biologic treatments or injections. If symptoms persist, evaluation by an orthopedic specialist like Dr. Yoon can help develop a personalized plan.
What is the difference between external vs internal impingement?
External impingement refers to tissue being pinched under a bone (the acromion) outside the joint, while internal impingement occurs within the joint between the ball and socket. Each type presents differently and may require tailored treatment approaches.
When should I see a specialist?
If pain persists despite rest or conservative therapy, or if you experience weakness or loss of function — especially if rotator cuff or labral damage is suspected — a specialist evaluation is recommended.
