Can Your Shoulder Pain Actually Come from Your Neck?

Your shoulder has been hurting for months, you have tried various things, but it never quite settles. In situations like this there is a possibility that is often overlooked: the source of the shoulder pain may not actually be the shoulder, but the neck. This article looks at why neck-related shoulder and arm pain happens, how it differs from pain that starts in the shoulder, and what actually helps.

Does shoulder pain always come from the shoulder?

No. Sometimes the source of shoulder pain is not the shoulder at all. Nerves run from the cervical spine out to the shoulder and down the arm; when a nerve root in the neck is irritated or under pressure, the pain can be felt in the shoulder — often together with numbness, tingling or weakness spreading into the arm or hand. In other words, the pain is in the shoulder, but the “problem” is the nerve in the neck. Medically this presentation is called cervical radiculopathy; in everyday language it is often described as a “pinched nerve”.

How can you tell: shoulder or neck?

So how do we work out whether the pain is coming from the shoulder or the neck? There are a few clues. If the pain stays only in the shoulder and appears with specific arm movements (lifting the arm, reaching for something), it is usually shoulder-related. But if the pain comes with numbness, tingling or weakness spreading into the arm or hand, and changes with neck movements (turning the head, looking up), the source is likely to be the nerve in the neck. Even so, these clues are not always clear-cut; the two can also exist side by side. What settles the question is the history and a physical assessment — which is why saying “my shoulder hurts” does not, on its own, tell us exactly where the problem lies.

Why won’t it settle? Focusing on the wrong place

The most frustrating part of this presentation is this: if the pain is coming from the nerve in the neck, approaches aimed only at the shoulder often do not deliver the expected result. The shoulder is strengthened, the shoulder is massaged, but because the source is the neck, the pain stubbornly persists. This wrong address is sometimes what lies behind “shoulder pain that hasn’t settled for months”. This is exactly why a proper assessment matters: directing treatment to the right place can be the key to a pain that will not go away.

How is it treated?

The good news is that most of these neck-related presentations improve markedly with structured, non-surgical physiotherapy; research shows the majority get better within a few weeks. Physiotherapy works in two ways here: on one hand it addresses the movement of the neck joints and the balance of the surrounding muscles with manual therapy; on the other, it uses techniques that support the irritated nerve’s ability to move freely and adapt to tension — neural mobilisation — reducing the basis for the pain to spread. The aim is not simply to dampen the pain, but to restore the healthy working of the nerve and the neck. For an overview of this and other shoulder and neck structures, see the Shoulder Problems page.

When is an assessment essential?

If your shoulder and arm pain comes with marked and progressive weakness (being unable to lift the arm, dropping objects), widespread loss of sensation, or symptoms affecting both arms at once, this calls for an earlier and more careful assessment. Such signs are uncommon, but it is important to have them checked promptly.
