Shoulder pain.

The shoulder trades stability for range.

Your shoulder moves further than any other joint in your body. It manages that by sitting in a shallow socket, held in place mostly by muscle and tendon rather than bone. That design is why you can throw a ball and scratch your own back. It is also why the shoulder gets irritated so easily.

Four small muscles, the rotator cuff, keep the ball centered in the socket while the big muscles do the moving. When one of those tendons is inflamed or frayed, lifting your arm out to the side hurts through part of the arc and eases past it. Sleeping on that side wakes you up.

Bursitis is inflammation of the small fluid sac that lets tendon glide under bone. It often rides along with cuff irritation, and the two are hard to separate by feel.

Frozen shoulder is different. The capsule around the joint thickens and tightens, and the shoulder loses range in every direction, including when someone else moves the arm for you. It has phases, it usually takes many months, and it needs patience and consistent motion work more than force.

The neck is part of this more often than people expect.

Nerves that run your shoulder and arm leave the spine in your neck. When a joint or disc in the neck irritates one of those nerves, the pain lands in the shoulder or the outer arm and the shoulder itself examines out clean.

There is a second link. A stiff upper back and a head that sits forward change where your shoulder blade rests. The blade is the platform your arm moves from. A tilted platform narrows the space the cuff tendons pass through, so the same overhead reach starts pinching. Treat the shoulder alone and it keeps coming back.

That is why Dr. Boss examines the neck, the upper back, and the shoulder blade at the same visit as the shoulder itself.

How Dr. Boss works out which one it is.

He starts by asking what you cannot do. Reach a top shelf. Fasten a seatbelt. Sleep on that side. Each of those points at a different structure.

Then he moves the arm through range while you relax, and compares that to what you can do on your own. A shoulder you cannot move but he can is usually a muscle or tendon problem. A shoulder neither of you can move is more likely a capsule problem. He runs specific tests for the cuff tendons and the bursa, checks strength, and tests the nerves down the arm. He also moves your neck to see whether that reproduces your shoulder pain.

Then he tells you what he found, in plain words, before anything gets treated.

What treatment looks like.

When the neck is driving it, we treat the neck. Adjustments restore motion to the segments that have locked up, and the arm symptoms usually follow.

When the shoulder itself is the problem, care is hands-on and gradual. Soft tissue work and massage therapy release the tight muscles pulling the joint out of position. Gentle joint work restores glide to the shoulder and the upper back. Therapeutic exercises then rebuild the cuff and the muscles that hold the shoulder blade down and back, which is what stops the pinch from returning.

For a frozen shoulder, the plan is steady daily motion work through what range you have, plus care for the neck and upper back so the rest of the limb does not stiffen with it. Progress is measured in degrees over weeks. Anyone promising a quick fix for a frozen shoulder is overselling.

What to expect.

The first visit takes about an hour: history, exam of neck and shoulder together, and a plan with a cost before you commit. We take most major plans and self-pay is available. Give us your plan details when you book and we will check your coverage before you arrive.

Cuff irritation caught early often settles inside a few weeks. Shoulders that have been sore for a year take longer, and how well you do the home exercises matters more than how many visits you attend. Dr. Boss will tell you what to expect at the start and check you against it as you go.
