Inflammation affecting the fluid-filled sac that provides cushioning for the acromion, a component of the scapula (shoulder blade), is known as subacromial bursitis. This condition arises when the bursa gets entrapped within the shoulder joint, often due to a fall or excessive use of the arm, such as in sports that involve throwing motions. This leads to pain and limited shoulder mobility, especially when raising the arm sideways.
Managing subacromial bursitis typically involves periods of rest, utilization of pain-relieving and nonsteroidal anti-inflammatory medications. Physiotherapy might also be recommended to sustain joint mobility. If the condition persists, an injection of corticosteroids into the affected joint might be necessary.
