mint melody tea. boil it over your stove let it cool or add lots of cold water so it's cool. take a wash cloth or paper towels and dip in the tea ring out so it isn't dripping wet but you do want it really damp then lay it on the burn area. repeat as needed. it takes the red out and the heat from the burn. It's a life savor around my house anytime someone gets a burn. we use it in summer for sunburns. but works for all Burns.
If it is really bad then I suggest you go to a urgent care or ER....burns hurt and can easily get infected. Having said that, there are several OTC medications that will help. You don't say where the burn is or anything so don't know the seriousness of the burn or what effect it may have.
solarcaine NO GELS or HEAVY OINTMENTS. they can hold bacteria in the wound no matter how soothing they may be and even anti bacterial ointments are no longer anti bacterial after a while. you need to see a Dr tho. you may need antibiotics in pill form and special burn care
Something to keep the air away from it, contact with air is where the pain comes from. I use Vaseline. Put a loose covering over it if it gets in the way when you're moving around, like gauze. If the skin is not broken you don't really have to worry about germs. if it is then Neosporin works well..Good luck.
