Swimmer's shoulder: pain from swimming and how to manage training load
Why shoulders get sore with swimming, how training load and technique play a part, how to adjust your sessions, and when to get it assessed.
Swimming asks a lot of the shoulder. A front-crawl swimmer can take thousands of strokes in a single session, so a rise in volume, a new training block, hand paddles or a return after time off can quickly outpace what the tendons around the shoulder are used to. 'Swimmer's shoulder' is a common name for pain that builds with this repeated overhead load.
When to get urgent help
Call 999 straight away if shoulder or arm pain comes with any of these. Shoulder pain can sometimes be referred from the heart.
- Chest pain or pressure, breathlessness, sweating or feeling faint, particularly with pain spreading into the left arm, neck or jaw
- A shoulder that looks out of place or deformed after an injury
- Sudden loss of the ability to lift your arm after a fall
What it can feel like
- A gradual ache at the front or top of the shoulder during or after a swim
- Pain as the arm enters the water or reaches overhead
- Stiffness or soreness the next morning that eases as you warm up
- Pain lying on the shoulder at night when it is more irritated
Common contributors
- A rapid increase in swim volume, intensity or frequency
- Adding hand paddles, pull buoys or new drills without building up gradually
- Fatigue late in sessions, when stroke control tends to fade
- Limited movement in the upper back or neck, or weakness in the muscles that steady the shoulder blade
- Stress, poor sleep and overall training load outside the pool
General self-care
These are general comfort measures many people find reasonable. They are not a treatment plan, and what suits one person may not suit another.
- Adjust rather than stop. Reduce volume or intensity, or swap in kick sets and lower-load work, while the shoulder settles
- Build back in small steps, changing one thing at a time (distance, intensity, paddles)
- Use a simple pain guide: mild discomfort that settles within a day is usually acceptable, while sharp or lingering pain is a signal to back off
- Add strength work for the shoulder and upper back, and keep the shoulder moving through the day
- Look after sleep, nutrition and rest days, which are part of training
When to see your GP
See your GP promptly, or call NHS 111, if you have any of the following:
- Pain after a fall or significant injury
- A hot, red, swollen shoulder, especially with a fever
- Unexplained weight loss or constant night pain unrelated to position
Consider seeing your GP if:
- Pain after a fall or sudden injury, especially if you cannot lift the arm
- Pain that is constant, wakes you at night regardless of position, or is not settling after a few weeks of sensible changes
- A hot, red, swollen shoulder, or numbness and tingling down the arm
Where an osteopath fits in
There is limited good-quality research showing that hands-on treatment changes the course of swimmer's shoulder, so I do not claim that osteopathy treats it.
What an osteopath can usefully do is assess the shoulder together with your neck, upper back and shoulder blade control, look at your recent training load, and guide a gradual return to the pool alongside an exercise plan. As a swimmer and endurance athlete myself, I know how hard it is to ease off, and gradual loading usually beats stopping altogether. An NHS trust leaflet describes exercise as the main recommended treatment for rotator cuff-related shoulder pain. If the assessment suggests you need your GP, a physiotherapist or a specialist instead, I will tell you.
If you would like your symptoms assessed, you are welcome to book an appointment. Osteopathic care is not right for everyone, and if something needs medical attention first, I will tell you.
Common questions
Can I keep swimming with a sore shoulder?
Often a modified version is possible: reducing volume and intensity, avoiding paddles and the aggravating strokes, and building back gradually. Pain that is sharp, lingers for hours, or builds through a session is a signal to back off.
How long does swimmer's shoulder take to recover?
It depends on how long it has been building and how well you can adjust load. An NHS trust leaflet on rotator cuff-related shoulder pain says improvement can take at least 12 weeks, with further gains possible up to 24 weeks.
