Shoulder pain is common, and it is not always the rotator cuff. Frozen shoulder, arthritis, neck problems, and even heart trouble can all show up there. Here is how to tell what might be going on, and when to see a doctor.
The shoulder is the most mobile joint in the body, and that mobility comes at a cost: it relies on muscles and tendons to stay stable. The rotator cuff is a group of four muscles and their tendons that hold the upper arm bone in the socket and let you lift and rotate your arm. Injuries or wear to the cuff are a very common cause of shoulder pain, but not the only one.
Rotator cuff or something else?
| Condition | Typical clues | Notes |
|---|---|---|
| Rotator cuff problem | Pain lifting the arm or reaching overhead, night pain lying on the shoulder, weakness | Can follow an injury or develop gradually with wear and overuse |
| Shoulder impingement | Pain with overhead movements, often a painful arc | Tendons rub against bone; often settles with rehabilitation |
| Frozen shoulder | Stiffness and loss of movement in all directions, even when someone else moves your arm | Tends to go through painful and stiff phases over a long period |
| Arthritis of the shoulder joint | Deep ache, stiffness and grinding, worse with activity | More common with age or after injury |
| Neck problem | Pain spreading from the neck, tingling or numbness in the arm | The shoulder may be fine; the nerve is irritated higher up |
How it is diagnosed
- History and examination: where it hurts, when, how it began, and tests of movement and strength.
- X-ray: shows the bones and any arthritis or bone spurs.
- Ultrasound or MRI: shows tendons and can show whether a tear is present and how large it is.
Imaging is only part of the picture. Many people have changes on a scan, particularly with age, that are not causing their symptoms, which is why examination matters.
Treatment options
- Relative rest and activity changes
Avoiding movements that provoke pain while keeping the shoulder gently moving.
- Physiotherapy
Strengthening and stretching programmes are the mainstay of treatment for many people, including many with partial tears.
- Medicines and injections
Pain relief as advised by your doctor. An injection around the tendon may be considered in some cases to settle pain and allow rehabilitation.
- Surgery
Considered if there is a significant tear, particularly after an injury, or if pain and weakness persist despite proper rehabilitation. Many repairs are done with keyhole (arthroscopic) techniques.
- Rehabilitation after surgery
A staged programme, with the arm protected at first. Your surgeon and physiotherapist will set the timetable for you.

Frequently asked questions
Q: How do I know if I have torn my rotator cuff?
Pain and weakness when lifting the arm, and night pain, are common clues, but only an examination and sometimes imaging can confirm a tear.
Q: Can a rotator cuff tear heal on its own?
Tears do not usually heal completely without surgery, but many people improve with rehabilitation and function well. The right choice depends on you.
Q: Is frozen shoulder the same as a rotator cuff injury?
No. Frozen shoulder is stiffness of the joint capsule, with limited movement even when someone else moves your arm. A cuff problem tends to cause pain and weakness.
Q: When should I see a doctor?
If pain lasts more than a few weeks, follows an injury, wakes you at night, or comes with weakness, numbness or tingling, get it checked.
Q: Can I get an opinion on my MRI?
Yes. Our partner orthopedic specialists can review your reports through a free, no-obligation second opinion.
Conclusion
Shoulder pain deserves a proper explanation rather than guesswork. A good examination, a sensible plan that starts with the least invasive option, and honest answers about whether surgery would really help will set you up for the best result.
