Overview
A clicking, popping, or catching sensation in the shoulder is extremely common, and on its own it isn't automatically a sign of something serious. Lots of healthy shoulders make noise sometimes without any pain or problem attached. What matters more is whether the clicking comes with pain, catching that briefly locks the movement, or a feeling that something is shifting out of place.
What This Symptom Feels Like
- An audible click or pop during certain arm movements, especially rotating or reaching overhead
- A "catching" sensation where the movement briefly hitches or locks before releasing
- Clicking that happens with no pain at all (often not concerning on its own)
- Clicking combined with pain, deep inside the joint or at the front of the shoulder
- A grinding or gritty feeling (sometimes called crepitus, a medical term for a grating sensation during movement) rather than a distinct click
- A sense that something is "catching" on something else inside the joint during a specific part of the motion
In plain terms: the shoulder joint has a lot of moving parts packed into a small space — tendons, a cartilage rim, and a bursa (a small fluid-filled cushioning sac) — all gliding past each other as your arm moves. Sometimes a tendon snaps slightly over a bony ridge, or a small fold of tissue moves out of place and back again, and that produces a click. If there's a frayed piece of cartilage or a rough joint surface, it can catch briefly during motion.
Common Causes
- Labral tear (SLAP lesion) — a tear in the cartilage rim of the shoulder socket, a common source of catching or a deep clunk
- Biceps tendinopathy — irritation of the biceps tendon as it runs through a groove at the front of the shoulder can cause a snapping sensation
- Shoulder impingement syndrome — tendons or bursa catching under the acromion during overhead motion
- Rotator cuff tear — a torn or frayed tendon edge can catch during certain movements
- Shoulder osteoarthritis — roughened joint surfaces can create grinding or clicking, especially in older adults
- Subacromial bursitis — an inflamed bursa can occasionally contribute to a catching feeling
- Acromioclavicular (AC) joint injury — clicking specifically at the top of the shoulder, at the small joint where the collarbone meets the shoulder blade
Clicking without pain is common and often just reflects normal tendon movement over bone. Clicking or catching with pain, or a sensation that the shoulder briefly locks or feels unstable, is more likely to be linked to one of the structural causes above.
Anatomy Usually Involved
- Glenohumeral joint — the main shoulder socket joint, where most clicking sensations originate
- Biceps brachii (long head) — a tendon that can snap or catch as it moves through its groove
- Subacromial bursa — can contribute to a catching feeling when inflamed
- Acromioclavicular joint — a common source of a localized click at the top of the shoulder
- Rotator cuff overview — frayed tendon edges can catch during movement
Questions to Ask Yourself
- Does the clicking happen with pain, or is it painless?
- Is there a specific moment in the motion where the shoulder briefly catches or locks?
- Does the click happen at the top of the shoulder (possibly the AC joint) or deep inside the joint?
- Did the clicking start after an injury, or has it been present gradually over a long time?
- Does the shoulder ever feel like it's about to give way or shift out of place along with the click?
- Is there any swelling, weakness, or reduced range of motion along with the clicking?
When It's Usually Minor
Painless clicking or popping that happens occasionally, without any catching, locking, or instability, is common in healthy shoulders and usually isn't a cause for concern. Many people notice this kind of clicking for years without any related problems.
When To Seek Medical Care
- Clicking or catching combined with significant pain
- A feeling that the shoulder is catching, locking, or about to give way
- Clicking that started suddenly after a fall, dislocation, or forceful injury
- Clicking combined with noticeable weakness or reduced range of motion
- Swelling, warmth, or other signs of joint irritation alongside the clicking
- Clicking that's getting more frequent or more painful over time
Self-Care Options
- If the clicking is painless, no specific treatment is usually needed — just monitor for changes
- If clicking comes with mild discomfort, avoid the specific movements that trigger it for a short period
- Build rotator cuff and scapular strength with exercises like scapular retraction row, which can improve overall joint control
- Warm up gradually before activity involving repetitive shoulder rotation
- Avoid forcing the shoulder through a catching sensation — ease off if it feels like it's locking
Related Symptoms
- Shoulder instability / feeling of giving way — often described together with catching or clunking
- Shoulder pain when reaching overhead — can occur alongside clicking in impingement-related conditions
- Shoulder weakness — may accompany catching when a rotator cuff tendon is frayed or torn
- Shoulder stiffness / reduced range of motion — a different mechanical sensation that can coexist with clicking
Related Injuries
- Labral tear (SLAP lesion)
- Biceps tendinopathy
- Shoulder impingement syndrome
- Rotator cuff tear
- Shoulder osteoarthritis
- Acromioclavicular joint injury
Related Exercises
- Scapular retraction row — improves shoulder blade control, which can reduce abnormal joint mechanics
- External rotation with band — supports rotator cuff strength and joint stability
- Isometric shoulder holds — low-irritation strengthening if clicking is accompanied by discomfort
