My husband got sunburned 5 weeks ago, and still has swelling and a dark red rash on his legs. He was given fluids and steroids at the time of the initial sunburn, and has since seen our doctor again. He prescribed him an antibiotic and some water pills to be used for 2 or 3 days. That was last Thursday, July 2, and now his legs are getting worse again. They are more red, and sowlen.
