A week ago I burnt myself, how long until it will stop hurting everytime i touch it?

I burnt myself, it's a pretty ugly burn. I burnt it on my wood-burning fireplace, like the metal door frame part, trying to put wood in. I washed it off with cool water, and now it's all scabs, but it still hurts whenever i touch it. When will this go away, both the hurting and the burnt spot???
