Got this burn today morning from a hot iron. I caused a little pain in the beginning and then stopped hurting.. when I came back to school and saw this burn which had now turned black, i googled and found out it's of the 3rd degree. I wanted to ask if this will heal back on its own in a few days or does it require medical care. A hospital is not close to my house so I'd be very inconvenient for me to go so but if it's very serious then I want to know so that i can get it treated! so please let me know what I should do. thanks
