Rotator cuff problems and shoulder 'impingement': scans, recovery time and exercise
What 'rotator cuff related shoulder pain' means, why scan findings often do not explain the pain, how long recovery tends to take, and how exercise is used.
The rotator cuff is a group of four muscles and their tendons that move the arm and keep the shoulder steady. An NHS trust leaflet says problems with this group account for up to 70% of shoulder pain. Terms such as 'impingement', 'bursitis' and 'subacromial pain' are older labels, and the leaflet now uses the broader term rotator cuff related shoulder pain.
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
- Pain in the shoulder and upper arm, sometimes felt into the neck
- Pain lifting the arm out to the side, reaching overhead or reaching behind your back
- Pain when lifting objects, or when lying on the affected arm
- A feeling that the arm is weaker or catches in some positions
Common contributors
- The NHS trust leaflet says pain typically appears when the load on the shoulder is more than the rotator cuff is currently able to cope with
- It can follow a sudden jump in activity, such as a day of gardening after the winter, or build gradually from small changes in daily activity
- An injury such as a fall can also trigger it
- Stress, poor sleep, excess weight and some long-term conditions can all make shoulder pain harder to settle
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.
- Keep using the arm as normally as you can. The leaflet says avoiding activity or resting for too long reduces the rotator cuff's capacity
- Pace your activity. Aim for a steady level, break big tasks into smaller chunks, and step closer to objects instead of reaching
- Rest the arm on a pillow when lying down, or put a pillow behind your back so you do not roll onto the sore side
- Exercise is the mainstay. The leaflet describes exercises that should feel challenging, with some pain that settles within a few hours acceptable, and advises doing them most days of the week
- Warmth or ice can be comfortable. If you use over-the-counter pain relief, follow the packet instructions or ask a pharmacist
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:
- Sudden loss of the ability to lift your arm after a fall or injury, or a shoulder that looks out of place. Seek urgent medical attention
- Pain that is not improving after 8 to 12 weeks, or is getting worse despite your exercises
- A hot, red, swollen shoulder, especially with a fever
- Pain that is constant, severe or wakes you every night regardless of position
Where an osteopath fits in
There is limited good-quality research showing that hands-on treatment changes the course of rotator cuff related shoulder pain, so I do not claim that osteopathy treats it.
What an osteopath can usefully do is assess the shoulder together with your neck and upper back, look at how you load the arm in daily life and sport, explain what a scan result does and does not mean, and help you build a graded exercise plan, which is the main recommended treatment. The leaflet says improvement can take at least 12 weeks, and you may not notice much change in the first six. 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
Do I need a scan for rotator cuff shoulder pain?
The NHS trust leaflet says ultrasound, X-ray and MRI are usually not needed. It also notes that common scan findings, such as thickened tendons or a thickened bursa, are often present in people with no shoulder pain, especially as we get older, so they often do not explain the pain.
How long does a rotator cuff problem take to get better?
The leaflet says improvement can take a minimum of 12 weeks and may continue up to 24 weeks, and that you may not notice much change in the first six weeks. It suggests seeing a physiotherapist if symptoms are not improving over 8 to 12 weeks, or are getting worse despite exercises.
Will a steroid injection fix my shoulder?
The leaflet says steroid injections may be considered in exceptional cases where pain stops you exercising. They may reduce pain for a while but do not address the cause, and repeated injections can harm the rotator cuff. Discuss this with your GP or a physiotherapist.
