Shoulder pain is more than just a minor inconvenience; it's a common issue that impacts millions of people across various age groups and lifestyles. From athletes to office workers, anyone can experience this discomfort. Identifying the main causes of shoulder pain can be essential for finding the right treatment. In this post, we'll explore the top five causes of shoulder pain and provide practical advice on managing each one.
1. Rotator Cuff Injuries
Rotator cuff injuries are among the leading causes of shoulder pain. The rotator cuff comprises four key muscles and tendons that work together to stabilise and move the shoulder joint. Injuries can result from sudden impacts or repetitive overhead activities like swimming or painting.
Symptoms might include:
Pain when reaching overhead or behind your back
Weakness in the shoulder when lifting objects
According to the American Academy of Orthopaedic Surgeons, about 2 million Americans seek treatment for rotator cuff problems each year. Treatment options can include rest, physical therapy, shockwave therapy, and, in severe situations, surgery.
2. Shoulder Impingement Syndrome
Shoulder impingement occurs when the rotator cuff tendons become irritated as they move through the shoulder joint. This often happens in individuals who frequently lift their arms above shoulder height, such as athletes or people doing overhead work.
Common symptoms include:
Pain when lifting the arm
Discomfort during activities like throwing or lifting weights
Research shows that approximately 50% of people with shoulder pain may have some form of impingement syndrome. Non-surgical treatments, such as physical therapy, shockwave therapy and corticosteroid injections, can be highly effective in relieving symptoms.

3. Frozen Shoulder (Adhesive Capsulitis)
Frozen shoulder, also known as adhesive capsulitis, leads to significant stiffness and pain in the shoulder. This condition often progresses slowly and might last for several months or even years.
People who have initially suffered from shoulder injuries are at a higher risk of developing frozen shoulder. Treatment typically involves:
Physical therapy to restore movement
Shockwave therapy to stimulate cell regeneration
Medication for pain relief
Corticosteroid injections to reduce inflammation
Statistics indicate that frozen shoulder affects about 3% to 5% of the general population, with women being more likely to experience it than men.
4. Arthritis
Arthritis is another major contributor to shoulder pain, especially in older adults. Both osteoarthritis and rheumatoid arthritis can lead to inflammation of the shoulder joint, causing pain and reducing mobility.
Approximately 10 million adults in the UK have some form of arthritis. For managing arthritis pain, individuals may consider:
Over-the-counter anti-inflammatory medications
In some cases, joint replacement surgery if conservative measures fail
5. Bursitis
Bursitis occurs when the bursae, which are small, fluid-filled sacs that cushion the joints, become inflamed. This condition often develops from repetitive movements, prolonged pressure, or an injury.
Symptoms of bursitis usually include:
Localised pain and swelling in the shoulder area
Discomfort when moving the shoulder or laying on it
Treatments often include rest, ice, and anti-inflammatory medications to alleviate pain and swelling.
Moving Towards Relief
Understanding the causes of shoulder pain can help you make informed decisions about your health. The top five sources we've discussed—rotator cuff injuries, shoulder impingement syndrome, frozen shoulder, arthritis, and bursitis—each have distinct symptoms and treatment options.
If you are experiencing persistent shoulder pain, it’s crucial to consult a healthcare professional. A tailored approach to diagnosis and treatment will give you the best chance for recovery.
Knowledge about your body and potential issues empowers you to take proactive steps toward managing and alleviating shoulder pain effectively.
