After a finger burn, it should immediately be rinsed with cold or running water continuously for at least half an hour to cool down the damaged skin. Then, use iodine or alcohol to disinfect the area, followed by covering it with a dressing. If swelling occurs, cold packs with ice water can be applied. Alternatively, magnesium sulfate wet compresses or more traditional remedies, such as continually applying potato slices, can help reduce the swelling. However, these methods will require some time to take effect. The main goal is to alleviate symptoms through anti-inflammatory and pain relief treatments, allowing the inflammation of the soft tissues to subside gradually and the swelling to reduce.
