Subacromial Bursitis: Why Your Shoulder Might Be Pinching
Do you feel a pinching pain in your shoulder when you lift your arm to the side or overhead? You might be experiencing a common condition called subacromial bursitis a type of shoulder bursitis that affects many people, especially women over the age of 50.
In this blog, we’ll explain what subacromial bursitis is, what causes it, how it’s linked to hormonal changes, and how osteopathy can help relieve pain and improve movement.
What is Subacromial Bursitis?
The subacromial bursa is a small, fluid-filled sac located in the shoulder between the acromion (the top of the shoulder blade) and the rotator cuff tendons. Its job is to reduce friction and allow smooth gliding of muscles and tendons when you move your arm.
Subacromial bursitis occurs when this bursa becomes inflamed or irritated, usually due to overuse, poor shoulder mechanics, or impingement (pinching) between the bones and soft tissues of the shoulder.
What Causes Subacromial Bursitis?
There are several common causes:
Repetitive overhead movements (e.g. painting, swimming, lifting)
Poor posture, especially rounded shoulders
Rotator cuff dysfunction
Direct trauma or injury to the shoulder
Degenerative changes from aging or osteoarthritis
Hormonal influences in peri- and postmenopausal women
The Role of Hormones in Shoulder Bursitis
Subacromial bursitis is particularly common in women over 50, and research suggests that hormonal changes during menopause may play a role.
As oestrogen levels drop, joint and tendon tissues become less elastic and more prone to inflammation. Combined with age-related changes like reduced muscle strength and posture issues, the shoulder becomes more vulnerable to irritation.
Common Symptoms of Subacromial Bursitis
Pinching or catching pain when lifting the arm sideways (abduction)
Heat or burning over the shoulder
Pain when lying on the affected shoulder
Dull ache or sharp pain at rest or with movement
Weakness or reduced range of motion
Swelling or tenderness over the outer shoulder
These symptoms can range from mild to severe and may interfere with daily activities like getting dressed or reaching overhead.
How Can Osteopathy Help with Shoulder Bursitis?
Osteopaths take a holistic approach to treating subacromial bursitis. We assess the entire shoulder complex, thoracic spine, rib cage, neck, posture, movement patterns and more to identify contributing factors.
Treatment may include:
Gentle hands on manual therapy to reduce inflammation and improve joint mobility
Myofascial release and soft tissue techniques
Dry needling, cupping, joint articulation, manipulation and more
Postural corrections and ergonomic advice
Rehabilitation exercises to restore shoulder strength and control
Guidance on activity modification to avoid aggravation
When to Seek Help
If your shoulder pain has lasted longer than a few days, or you’re noticing weakness or limited movement, it’s important to get assessed. Early treatment can prevent chronic changes and improve your recovery time.
Subacromial Bursitis Is Common, But Treatable
If you're over 50, experiencing shoulder pain, and suspect subacromial bursitis, you're not alone. It’s a very common shoulder condition, but it doesn’t have to slow you down. With targeted osteopathic care, you can reduce inflammation, restore movement, and get back to doing the things you love.
