Rotator cuff injury: The rotator cuff is a group of muscles and tendons that stabilize the shoulder joint. Overuse, repetitive motions, or sudden trauma can lead to tears or inflammation in the rotator cuff, causing pain and limited range of motion.

Here are some common causes to consider:

Also known as adhesive capsulitis, this condition involves the gradual stiffening of the shoulder joint. It can result from injury, prolonged immobilization, or certain medical conditions, causing pain and restricted mobility.

Frozen shoulder

Arthritis can affect any joint, including the shoulder. Osteoarthritis, rheumatoid arthritis, or post-traumatic arthritis can lead to chronic shoulder pain, swelling, and limited joint function.

Shoulder arthritis

Bursae are small fluid-filled sacs that cushion the bones, tendons, and muscles in the shoulder joint. When these bursae become inflamed, often due to repetitive motions or injury, it can result in shoulder pain and swelling.
