When you burn anything with anything, immediately put cold water or ice on it for about 10 minutes. Nothing else!!
However, since you have written this, it is a little late to do that.
If the skin isn't off the burn, merely apply some spray meant for sunburn, aloe, hydrocortisone cream, or any other analgesic to help stop the pain, cover with a bandaid and wait it out to heal. If you have a blister DO NOT PRICK THE BLISTER TO LET THE FLUID OUT!!!!!!!
Most people do not realize that fluid there is the body's defense against infection and to protect and heal the burn.
Cover it with gauze or bandaid and protect the area so the blister doesn't break. If it breaks on it's own, just keep it covered and keep the skin over the area.
To have the area with no skin over it is asking for a lot of trouble.....especially infection. In that case, keep triple antibiotic ointment on it and cover with bandaid. Don't get it wet....if you do, replace everything immediately.
It should heal without problems

P.S. Rubbing butter or any kind of oil on it is an old wives tale that has been handed down from grandma's day. Please, the grease will hold the heat in and cause it to heal very slowly and doesn't do a thing for the pain or healing.
