I have a bad sunburn on both my legs with my ankles swelling and skin is really tight. I am hardly able to walk or stand without pain and can barely stretch my legs due to the skin tightness. I have used aloe with methanol, over the counter burn cream and 100% aloe. I also have been taking cold showers and trying to drink a little more water. It is only the second day after my sunburn. Is there a different treatment I can use.
