A second-degree burn is a type of burn that affects both the outer and underlying layers of the skin. It is characterized by painful blisters, redness, and swelling. Burns of the second degree are classified into three categories: superficial partial-thickness, deep partial-thickness, and full-thickness burns. When multiple sites of the lower limb, except the ankle and foot, are affected, it is called a burn of the second degree of multiple sites of unspecified lower limb, except ankle and foot.
The most common causes of second-degree burns on the lower limb are exposure to hot liquids, flames, and hot objects. Electrical burns, chemical burns, and sunburns can also cause second-degree burns. Symptoms of this type of burn include pain, redness, swelling, and blistering. In severe cases, the skin may appear white or blackened and may have a leathery texture.
In conclusion, a burn of the second degree of multiple sites of unspecified lower limb, except ankle and foot, is a painful and potentially serious injury. It is important to take immediate action to cool and clean the affected area and seek medical attention if necessary. With proper treatment, most second-degree burns will heal within a few weeks.
