What Is Bursitis of the Shoulder?

What Is Shoulder Bursitis?

Shoulder bursitis occurs when inflammation affects the bursa, which is a tiny sac filled with fluids in the shoulder. This part is important for reducing friction between the connective tissue and bones, thus allowing bones, muscles, and tendons to move together. Overuse of the shoulder or injuries may cause fluids to build up in these area, thus leading to bursitis. When the condition happens, swelling would come on suddenly or gradually and affect certain movements in the daily lives. [1]

Types of Shoulder Bursitis

Shoulder bursitis can be categorized into three main types:

– Acute Bursitis: This form occurs suddenly, typically after an injury or accident. You may feel painful when moving or touching the shoulder.

– Chronic Bursitis: Recurring acute bursitis or recurring injuries may lead to chronic bursitis of the shoulder. This form is the most common one. People may experience alternate periods of flare-ups and no symptoms that last a few months. This would lead to persistent inflammation and weakness of the shoulder and arm.

– Infectious Bursitis: This rare form often occurs after a bacterial infection. The shoulder would become purple, red, and warm to the touch. [2]
