Shoulder arthritis refers to the degeneration of the shoulder joint cartilage, leading to pain, stiffness, and limited range of motion. It can be caused by various factors, including age-related wear and tear (osteoarthritis), autoimmune conditions (rheumatoid arthritis), or previous shoulder injuries. Individuals with shoulder arthritis often experience persistent pain that worsens with movement and weight-bearing activities. They may also have stiffness and a decreased ability to move their shoulder freely. Swelling and tenderness in the affected area can also occur. Treatment options for shoulder arthritis include non-surgical approaches such as pain management, physical therapy, and lifestyle modifications. In more severe cases, surgical interventions like joint replacement may be recommended.
