Shoulder bursitis refers to inflammation of the shoulder bursa. Bursa are small, fluid-filled sacs that help to cushion movement and prevent friction in the joints. Bursa contain a lubricating substance called synovial fluid, which aids in the cushioning effect. They are usually present in areas subject to movement, such as between the bones, tendons and muscles near the joints.
The shoulder contains a large amount of bursa as it is one of the largest joints in the body, which is why it is the area most commonly affected by bursitis. Symptoms of shoulder bursitis usually include tenderness, pain, heat and swelling. Movement may be limited due to stiffness. Pain is often worse in the morning or after physical activity.
Shoulder pain may also be caused by subacromial bursitis, which can occur when shoulder bursa are trapped and compressed between your rotator cuff tendons and bone (acromion) during shoulder movements. Depending on the injury, shoulder bursitis treatment is sometimes the best way to experience healing from the injury.
Causes of Shoulder Bursitis
Bursitis is often caused by strenuous or repetitive activity of the shoulder area. Activities that involve overuse such as throwing, lifting, or digging are common contributors. Sports such as baseball, football and basketball have high incidences of shoulder bursitis.
In other cases, a single injury or trauma to the shoulder can result in bursitis, particularly falls or collisions.
Inflammatory conditions such as rheumatoid arthritis or systemic lupus erythematosus may also lead to irritation of the shoulder joint and subsequent bursitis. Bursitis may also occur for no apparent reason.
Preventing Shoulder Bursitis
Reducing the risk and severity of shoulder bursitis can be as simple as changing a few lifestyle routines. Patients should avoid carrying heavy loads where possible, and take frequent breaks from repetitive activities that involve the shoulder, such as digging or painting.
Exercises that help to strengthen the surrounding muscles in the shoulder are also advised. Warming up the shoulder before physical activity also helps to reduce trauma to the area. Stretching the shoulder and arm muscles after physical activity can ease muscle strain and reduce inflammation.
Shoulder Bursitis Treatment
Treatment is of shoulder pain should not be delayed. When left untreated, shoulder bursitis can lead calcium deposits building up in the soft tissues, known as calcific bursitis. This may permanently limit or inhibit movement of the shoulder.
Shoulder bursitis treatment usually begins with reducing the inflammation. This may be done by applying ice compresses to the area, which help to relieve swelling. Rest is also advised. The patient may be fitted with shoulder sling to support the joint and prevent movement. A doctor or health practitioner will usually prescribe pain relief medication.
Severe bursitis may require fluid to be removed manually from shoulder bursa in order to relieve pressure. This kind of shoulder bursitis treatment is known as aspiration, and is done with a needle and syringe. Shoulder surgeons can also be a huge help in sorting out proper treatment. A shoulder bursitis treatment program usually involves some form of physiotherapy to help restore movement in the shoulder muscles. Alternative therapies such as acupuncture, massage and chiropractic may be recommended for helping to relieve pain and strengthen the area.
If necessary, corticosteroid injections can help to reduce inflammation and improve mobility.
Surgical removal of the damaged bursa is rarely necessary, but may be advised if bursitis is both severe and chronic.
