One form of relief is to soak in an oatmeal powder bath. This help sooths the skin. After your bath, lather yourself in aloe-vera gel. Be sure to use the non-mentholated kind, because the mentholated aloe may sting.
You can try to apply some ice packs or ice to the burn area. It will help to reduce the inflammation and reduce/ minimise the pain. Also keep the area opened to dry air and avoid bandaging it.
