Glad its clearing up! Rashes are tough to pin down a cause, especially after swimming. Water, especially standing pools of water are full of plant and animal products and waste so it could be an allergic reaction to anything. Since he had such a bad reaction he might consider having an allergy scratch test performed. Your doctor or dermatologist will scratch the skin lightly and then put an ointment with various extracts on it to see what gets a reaction. If its a serious allergy it could help him avoid whatever it is and potentially save his life if he has a serious reaction. Just a thought.
