S40-S49: Injuries to the shoulder and upper arm

S40: Superficial injury of shoulder and upper arm

Superficial injuries of the shoulder and upper arm refer to a group of conditions resulting from a direct blow, undue strain, or abrupt twisting motion affecting the upper portion of the arm. They include but are not limited to abrasions, bruises, or superficial burns. Causes often involve common everyday accidents such as falls, sporting incidents, or minor automobile mishaps. These injuries generally present as mild pain, skin discoloration or tenderness, and sometimes swelling in the affected area. Although the damage primarily involves the skin and surface tissues, the progression or severity can vary based on the type and force of the initial trauma. Most importantly, while the injury may be superficial, the discomfort can extend into the deeper tissues, including muscles and potentially affecting motions of the arm and shoulder. With time, these symptoms tend to recover gradually as the body's healing process takes place.
