S.S.
Oh my gosh! I thought my son was the only one who got that. :) He had the same rash you are describing, but with no fever. We just assumed it was irritation from the sand, or bug bites like others have mentioned. They went away quickly (within a day or two) on their own though, with no treatment necessary, he said they didn't itch and weren't uncomfortable at all. It just made me uncomfortable to look at it! Maybe the fever is caused by something else?
