Shoulder pain relief
Where it hurts tells you why
Shoulder pain doesn't show up randomly. Each location has a short list of likely drivers, and identifying which one you're dealing with is the first step toward actually fixing it instead of chasing the symptom around.
The shoulder is four joints, not one
When people say "my shoulder hurts," they usually mean the glenohumeral joint, the ball-and-socket where the arm meets the body. That's only one of four joints that have to cooperate for the arm to work. There's also the acromioclavicular (AC) joint at the top of the shoulder, the sternoclavicular joint where the collarbone meets the chest, and the scapulothoracic articulation where the shoulder blade glides across the rib cage.
Pain in any of these gets filed under "shoulder pain" by the person experiencing it. Which joint is actually generating the pain, or whether it's the soft tissue around any of them, is what location tells you.
Pain on the front of the shoulder
This is the most common presentation, and the usual suspects are the biceps tendon, the subscapularis, and the front capsule of the glenohumeral joint.
Biceps tendinopathy shows up as pain right at the front of the shoulder, sometimes radiating a few inches down the upper arm. It hurts more with reaching forward or lifting something in front of you. The usual driver is a humeral head that's migrated forward in the socket because the rotator cuff isn't holding it centered. Treat the cuff and the scapula, and the biceps tendon stops taking the beating.
Front-capsule pain tends to feel deeper and more internal. It's often an impingement pattern, where tissue is being compressed as you raise the arm. The driver, almost always, is the scapula not rotating upward properly as the arm lifts. The subacromial space narrows, tissue gets pinched, pain fires. Treating the scapular pattern usually clears it.
Pain on the top of the shoulder
This is usually the AC joint or the upper trapezius. The distinction matters because they want different treatment.
AC joint pain sits exactly on top of the shoulder, where you can feel a small bump. It's sharper and more focal, often worse with reaching across the body (think seatbelt) or sleeping with the arm overhead. AC joints take a lot of load from bench pressing, pushups, and landing on the shoulder. They can get arthritic or inflamed, and the tissue around them can benefit from hands-on release work once the acute inflammation settles.
Upper trap pain feels more like a rope of tension running from the neck out to the top of the shoulder. This is almost never a shoulder problem in the anatomical sense. It's a breathing, posture, and stress pattern, covered in detail on the neck-and-shoulder-tension page.
Pain deep inside the shoulder
The vague "it's somewhere in there" pain that's hard to point to usually originates in the joint capsule, the labrum, or the deeper rotator cuff muscles (supraspinatus, infraspinatus, teres minor).
A labral tear is more common than people realize, especially in overhead athletes, climbers, and surfers. It presents as a deep clicking or catching sensation with specific movements, sometimes with a feeling of instability. Imaging confirms it. Most small labral issues respond well to conservative care that improves cuff function and scapular position, which reduces the stress on the torn tissue and often lets it settle.
Adhesive capsulitis, also called frozen shoulder, presents as a progressive loss of range of motion with pain, typically over several months. It has distinct phases and is worth identifying early because the treatment timeline differs from other shoulder conditions. Hands-on fascial work, gentle progressive loading, and patience are the reliable path. Pushing hard through a frozen shoulder usually prolongs it.
Pain on the back of the shoulder blade
This is almost always referred from somewhere else. The shoulder blade area, particularly the medial edge near the spine, is a common landing site for pain generated by the neck (cervical disc or facet issues) or the mid-back (rhomboid dysfunction, rib restriction).
When someone points to the edge of their shoulder blade and says "it's been nagging for months," the treatment is usually upstream at the neck and thoracic spine, not at the shoulder blade itself. This is one of the more commonly mistreated patterns, because people keep massaging the sore spot while the actual source keeps generating the referred pain.
Pain that radiates down the arm
Pain that travels from the shoulder down toward the hand is a neurological signal, not a muscular one. The usual source is the neck, where nerve roots can be irritated by disc issues, facet stiffness, or soft-tissue compression. Thoracic outlet syndrome is another cause, where the nerves and blood vessels passing through the first-rib area get compressed by tight scalenes or a dropped rib.
This is the presentation where I'm most likely to suggest seeing a physician first, or at minimum that we work in coordination with one. Hands-on work on the neck and first rib can relieve a lot of radicular symptoms, but persistent or severe radiation deserves a proper workup to rule out structures that need imaging.
What to do with this information
Location is a useful starting point, not a diagnosis. The value is knowing roughly where the conversation should begin. A front-of-shoulder pattern gets addressed differently from a top-of-shoulder pattern, and both differ from a radiating pattern. Treating the wrong one is how people end up in long therapeutic relationships that don't help.
In practice, most shoulder pain I see in the office has multiple contributors layered together: a primary driver, some compensations around it, and a bit of inflammation sitting on top. Sorting out which is which is what the first session is usually for. Once we know the actual pattern, the work is focused and tends to move quickly.
Get an honest read
If you've been chasing shoulder pain and it keeps moving, changing, or returning after treatment, a Body Systems Check is where I'd start. I'll assess the joint, the scapular pattern, the neck, the breath, and the full chain up to the rib cage, and give you a specific picture of which driver is actually running the show. From there, the plan is clear. If you'd like to see what my treatment approach looks like in detail, there's a companion page at shoulder pain treatment.
Questions, answered
How do I know if my pain is actually in the joint or somewhere else?
+
A few quick self-tests help. Pain at rest that doesn't change with movement usually points at the joint or something inflamed. Pain that only shows up with specific movements and is quiet at rest usually points at tissue patterns rather than structural damage. Pain that radiates down the arm often involves the neck. None of these is diagnostic on its own, but together they're useful signals to bring to either an MD or a bodyworker. If the pain is severe, worse at night, or accompanied by weakness, see a doctor first.
What's the difference between 'tendonitis' and a rotator cuff tear?
+
Tendonitis is inflammation of a tendon, usually from overuse or faulty mechanics. It's painful but the tendon is intact. A tear is actual disruption of the tendon fibers. Minor tears often heal with conservative care. Large tears sometimes need surgical consultation. Imaging is how you tell the difference, and most people with tendonitis-pattern shoulder pain don't need imaging because the symptoms and movement exam are distinctive. If pain persists after six weeks of thoughtful conservative care, imaging becomes useful.
Is it normal for my shoulder to crackle when I move it?
+
Often yes. Crepitus, the clicking or cracking you hear, is usually the sound of tissue sliding over bone or air bubbles shifting in joint fluid. On its own, it's not a problem. What matters is whether the crepitus is painful. Silent crackle: no concern. Crackle that coincides with pain or catches: worth evaluating, because it can indicate the joint is tracking poorly.
My shoulder hurts only at night. What's that about?
+
Night pain is a specific signal. Lying on the affected side compresses the tissue and irritates inflamed structures. The classic culprits are subacromial impingement (pain when the arm is pressed into the body) and bursitis. It's also the most common reason someone finally schedules an appointment, because sleep loss adds up fast. Conservative care usually resolves night pain within a few weeks, but it's a flag worth taking seriously because pain bad enough to wake you up tends to worsen faster than pain you can mostly ignore.
