I went to the beach the other day, and had gotten a very bad sunburn (in the outline of my two-piece bathing suit-oops) and two days later, I woke up with a rash in the areas of my body which were not burnt, which include under my chin, around my chest (where my bathing suit covered)
and also behind my knees. It is speckled,
and has become very itchy
and is spreading as the day goes on. What is it, and how do I make it go away!? HELP!
