Suggest Remedy For Discoloured & Swollen Skin

Hello. I burned my hand about 6hrs, ago, due to hot water. It hasn't blistered, but it still stings. The only relief I get is when I place my hand under cold running water. The skin is a little bit discolored (darker), and my hand seems to be a little swollen, but other than that the only issue I'm having is the stinging. Is there anything I can do at home for the stinging?
