Shoulder pain is a common complaint that can stem from any of the various structures within the shoulder joint or the surrounding muscles, ligaments, and tendons. The shoulder is a complex, highly mobile structure made up of several components, the joint itself is a ball-and-socket type, primarily involving two specific joints: the glenohumeral Joint and acromioclavicular (AC) Joint.

Causes of Shoulder Pain:

• Rotator Cuff Injuries: These include tears and tendinitis, often resulting from overuse or acute injury, affecting the muscles and tendons that stabilize the shoulder.

• Impingement: Occurs when the rotator cuff gets caught between the acromion and humeral head, especially during overhead activities.

• Frozen Shoulder: Also known as adhesive capsulitis, this is characterized by stiffness and pain in the shoulder joint caused by inflammation and fibrotic adhesions.

• Arthritis: Osteoarthritis can develop in the shoulder, causing the cartilage to wear down and the joints to inflame.

• Fractures: Injuries to the bones around the shoulder, such as the clavicle or humerus, can cause intense pain and immobility.

• Instability: Can occur if the head of the humerus is forced out of the shoulder socket, often from trauma or overuse, leading to dislocation or subluxation.

Impact on Life: Shoulder pain can significantly impair an individual's ability to perform daily activities, especially those that involve lifting, reaching, or any movement that requires arm mobility. Difficulty in performing routine tasks such as dressing, driving, and sleeping due to pain or discomfort can result in poor sleep quality and reduced overall physical activity. This condition can be treated by shoulder injections (corticosteroids, platelet-rich plasma, hyaluronic acid), peripheral nerve stimulation, peripheral nerve blocks, hyaluronic acid injections, platelet-rich-plasma injections.
