S46: Injury of muscle and tendon at shoulder and upper arm level

The category "Injury of muscle and tendon at shoulder and upper arm level" comprises a variety of conditions that involve damage to the muscles or tendons in the shoulder and upper arm area. These injuries might be due to various causes, including strain from overuse, a direct blow or fall, a sudden jerk or pull, or an awkward movement. The common symptoms of these conditions can vary but often include pain, swelling, bruising, difficulty in moving the affected area, and in severe cases, inability to use the arm. Depending on the severity and specifics of the injury, symptoms might appear immediately, or gradually over time. As these injuries involve the muscular and skeletal systems, they can impact day-to-day tasks and movements. Over time, without appropriate care, these injuries might lead to chronic pain, restricted motion, or development of conditions such as frozen shoulder. The exact progression of these conditions often depends on the specific type and severity of the injury, as well as personal factors such as overall health, age, and adherence to prescribed care.
