S90: Superficial injury of ankle and foot

Superficial injuries of the ankle and foot typically refer to mild, surface-level traumas that affect the skin and underlying soft tissues of these regions. They often result from accidents or environmental hazards, such as stubbing your toe, stepping on something sharp, or scraping your foot or ankle. Symptoms can include pain, swelling, redness, skin abrasions, blisters, or bruising on the area of the foot or ankle affected. It's common to experience some discomfort or difficulty with walking or wearing shoes, particularly in the early stages of injury. The progression of these injuries can vary but often involves an initial period of inflammation and discomfort followed by gradual healing. The integumentary (skin) system is primarily affected, although depending on the location and severity of the injury, the musculoskeletal system may also be involved.
