Burned fingers should not be wrapped up. A finger burn occurs when the skin and soft tissues of the finger are damaged by hot water, causing an inflammatory response, which can lead to symptoms such as redness, swelling, heat, and pain, and severe cases can cause necrosis of the skin and dermis. If wrapped up, the temperature of the burned finger cannot decrease, which might worsen the degree of the burn. Generally, after a finger burn, it is advisable to quickly soak or rinse the finger in cold or running water for at least about half an hour to lower the temperature of the finger. This can reduce the severity of the burn and thus protect the finger.
