Overload and age-related changes can cause tendinopathy (often called tendinitis), the most common cause of shoulder pain in adults. ## Symptoms - Pain on the outer side of the shoulder and upper arm - Pain when lifting the arm to the side or overhead - Night pain, especially lying on the affected side - Weakness in some patients Further reading: the [guide “Shoulder Pain”](https://drmotiva.com/en/guides/shoulder-pain/) and the articles [Hip Pain: Common Causes and Treatment](https://drmotiva.com/en/articles/hip-pain-causes/) and [Hip Impingement (Femoroacetabular Impingement Syndrome)](https://drmotiva.com/en/articles/hip-impingement/). ## Diagnosis Clinical examination is usually sufficient; ultrasound or MRI can show tendon changes and tears [1]. ## Treatment Current clinical guidance recommends exercise-based rehabilitation as the main treatment [1, 3]: - Progressive strengthening and range-of-motion exercises - Activity modification and education - Pain medicines and, in selected cases, a corticosteroid injection for short-term relief A large trial found that arthroscopic subacromial decompression was not better than placebo surgery for subacromial pain [2], so surgery is not routinely recommended for tendinopathy without a significant tear. ## Why it develops The supraspinatus tendon passes through a narrow space beneath the acromion (the bony roof of the shoulder). Repeated overhead activity, sudden increases in load, reduced muscle control around the shoulder blade and age-related changes in the tendon can lead to tendinopathy (tendon pain with changes in its structure). Over time, the tendon may develop partial or full tears, although many tears cause no symptoms. ## Risk factors - Age over 40 - Repetitive overhead work, such as painting or construction - Overhead sports, such as tennis, swimming and volleyball - Smoking and diabetes, which are associated with tendon problems - Weakness of the rotator cuff and shoulder-blade muscles ## Assessment in practice The examination tests shoulder movement, strength and pain-provoking manoeuvres, and also checks the neck, because neck problems can mimic shoulder pain. Ultrasound is a practical way to assess the tendon and look for tears or calcium deposits (calcific tendinopathy). X-ray shows bone and calcification. MRI is used when a significant tear is suspected or surgery is being considered. ## Rehabilitation - Pain-modulating exercises early on, within tolerable discomfort - Progressive rotator cuff and shoulder-blade strengthening - Gradual return to overhead work or sport - Programmes usually last at least 12 weeks The programme is planned by your physical medicine and rehabilitation specialist and the physiotherapist. Whether an injection is suitable is decided after examination; repeated corticosteroid injections are generally avoided because of possible effects on the tendon. ## Home measures - Reduce, rather than stop, painful overhead activities for a period - Keep the arm moving within comfort - Sleep with a pillow supporting the arm, or on the other side - Use ice or heat for comfort - Continue the exercises regularly, even after the pain improves ## Red flags Seek prompt assessment for sudden loss of strength after a fall or lifting injury (possible acute tear), a hot swollen shoulder with fever, or shoulder pain with chest pain or shortness of breath. ## When to see your physical medicine and rehabilitation specialist Seek assessment if pain is severe, keeps getting worse, wakes you at night or does not start to improve within a few weeks; if numbness, weakness or any warning sign appears; or if you are unsure what your test results mean. Your physical medicine and rehabilitation (PM&R) specialist, a doctor trained to diagnose and treat musculoskeletal and nerve problems without surgery, examines you, explains the findings and plans treatment together with the physiotherapist. Whether injections or other advanced treatments are suitable for you is decided by a PM&R specialist after examination. Prof. Dr. Engin Çakar works in this field and can be consulted online or in person; otherwise, please consult a PM&R specialist near you. To make the most of the consultation, it helps to bring: - A short timeline of your symptoms and what makes them better or worse - A list of your medicines and other health conditions - Previous imaging (the images themselves, not only the reports), test results and treatment summaries - Your questions and goals, such as returning to work, sport or a particular activity ## Frequently asked questions **Should I rest the shoulder completely?** No. Relative rest from painful activities with continued exercise is better. **How long does recovery take?** Usually weeks to months with consistent exercise. See [Frozen shoulder](https://drmotiva.com/en/articles/frozen-shoulder/). **Is a partial tear the same as tendinitis?** Not exactly, but both are often treated first with exercise-based rehabilitation. Larger acute tears in active people may need a surgical opinion. **Is pain during exercise acceptable?** Mild, tolerable pain that settles within a day is usually acceptable; your exercise load should be adjusted if pain keeps increasing. ## Assessment and contact You can request an appointment or a second-opinion review of existing reports and imaging: [Contact & second opinion (WhatsApp)](https://drmotiva.com/go/wa?l=en&t=&loc=inline_contact&p=%2Fen%2Farticles%2Fsupraspinatus-tendinitis%2F).
