Damage to the skin or underlying tissues. Any type of injury to the skin poses a threat due to the risk of infection or further damage if the wound becomes complicated.

Wound symptoms and healing times can vary greatly. The primary symptom of all wounds is the pain to a lesser or greater degree. Bruising and/or bleeding can also occur. If left untreated, wounds can also lead to infection.

Types: There are many types of wounds, including superficial paper cuts, surgical wounds, pressure sores, diabetic ulcers, and wounds due to trauma (accidents, cuts, etc.).

Acute wounds can be as simple as a minor cut or scratch that require little more than cleansing and bandaging, or as complicated as a wound requiring surgical closure (stitches or suturing) or even greater care. Chronic wounds, such as arterial, venous, or diabetic ulcers, may involve greater time for healing to occur.

Wounds can be caused by cuts, surgical procedures, bites, or trauma (blows to the body), or they can result as a complication of a disease, such as diabetic ulcers, or from prolonged bed rest (bed sores).
