Trying to dx a rash that my nephew has who is 6, one is the size of a 50 cent piece round and raised, looks like a first degree burn looks raw red and gets a blister and leaks clear fluid, has 3 on his legs one between his toes, one on his stomach by his waist band and now starting to get bumps on is face, he was taken to the dr and thought to be swimmers itch, or a reaction to mysquoite bites, they are itchy and at times painful.
