What do you do if you get too much sunburn?

First, do something to heal the wounds. Cover them if you are exposed ot the sun again, to prevent them from getting worse. There are creams and lotions made to help heal sunburns, too. If it is very severe, go to the doctors. They can help with more proactive treatments to help prevent future problems. For the pain, you could try an oer-the-counter pain killer to help ease it up a little but, too.
