Wounds are injuries to the skin or underlying tissues that result in a break or opening, which can range from minor cuts and scrapes to deep lacerations or puncture injuries. They may be caused by trauma, surgery, burns, or pressure and can vary in severity, depth, and risk of infection. Symptoms of wounds include pain, bleeding, swelling, redness, and sometimes exposure of underlying tissues. Proper healing involves a complex process of clotting, inflammation, tissue formation, and remodeling, and complications such as infection, delayed healing, or scarring can occur depending on the wound type and care. Wounds can affect skin, muscles, blood vessels, and other tissues, making assessment and appropriate management important for recovery.
