What you should do depends on how bad the burn is, if the area that was burned is red and swollen/blistered then it is probably a 2nd degree burn. If the burn has blisters that are not open, first remove any clothing or jewelry from the injured area. Then, hold the burned area under cool running water for around 10 minutes to stop the burning process. You can also use a clean towel or wash cloth moistened with cold water. However, don’t use ice or ice water because they will further damage the tissue. Do not break open the blisters, or there will be a greater risk of infection. If the blisters are open, don’t remove any clothing that might be stuck to the burn, and don’t run water over the burn. Use sterile gauze to bandage the burned area, you should change the bandage daily. Make sure to keep the bandaging relatively loose to make sure air can still get at it. Try to keep your hand raised to reduce swelling. Putting butter,creams, or ointments can actually slow down the healing and make the burn worse because air can't escape, if you do decide to put something on it, make sure it won't trap the heat in. In fact, you should probably go online yourself to find something that might work. Hope this helps!
