Swimmer's shoulder: why it happens and what fixes it

Swimming gets recommended constantly as the joint-friendly option, and for most people it is. But competitive and regular lap swimmers do something no other athlete does: they take the shoulder through full overhead rotation thousands of times per session. Casey has strong aquatic participation across its leisure centres, and shoulder pain is the reason most swimmers come to see us.

What "swimmer's shoulder" actually is

It is not one diagnosis. Most cases are subacromial irritation, rotator cuff tendinopathy, or a combination, driven by the volume of overhead repetitions. The tissue is not damaged so much as overloaded relative to what it can currently tolerate. Our shoulder pain page covers the presentations in more detail.

Stroke mechanics matter

Two things show up repeatedly. Crossing the midline on entry increases the compressive load at the front of the shoulder. Insufficient body roll forces the arm to clear the water through the shoulder alone rather than with the trunk. Both are coachable, and both reduce the load more effectively than any exercise we can prescribe.

The mid-back connection

A stiff thoracic spine forces the shoulder to find range it does not have. Swimmers who sit at a desk all day and then swim in the evening are asking an already-restricted mid-back to allow full overhead movement. Improving thoracic rotation often reduces shoulder pain without touching the shoulder itself — see upper back pain.

Volume and paddles

Two changes account for a large share of the swimmer's shoulders we see: a sudden increase in weekly distance, and the introduction of hand paddles. Paddles increase the load on the shoulder substantially and are best added gradually rather than at full volume.

When to come in

Pain that persists after the warm-up, pain at night lying on that side, or pain that has made you change your stroke are all worth assessing. Continuing to swim through it usually extends the recovery rather than shortening it.

What a first appointment looks like

We start with what actually happened and what the demands of your sport are, then assess the injured area alongside the joints and muscles above and below it — because the painful structure is often not the limiting one. You get a diagnosis, a realistic timeframe, and a plan that accounts for your training and match schedule rather than assuming you can stop. If we think you need imaging or another practitioner, we will say so at that first visit rather than after six sessions.
