My 4.5 yo DS got a pimply rash all over his buttocks on Thursday. I assumed it was some type of bug he caught at the pool earlier that day. I gave him a shower after swimming & a bath later that night when I first noticed them, but they were still there the following day. I put some zinc oxide on them, still assuming it was some sort of irritation, in an attempt to dry them out. They finally did start going down. He never got more on the rest of his body, and they didn't itch him at all, but his butt was pretty thoroughly covered (though his anus was not irritated). I still wipe his bum after stools, so I know he's clean and it wasn't a hygiene issue.
On Sunday, he started developing a mild cold. Monday, he was sneezing with a runny nose all day. Tuesday he developed a fever and had little energy. He's finally starting to feel better today (Wed). Still has a few bumps, but most have gone. To my knowledge, he hasn't been exposed to anyone lately that may have had the pox. Is that something you could pick up at a pool? Anyway, if that was the pox, I'm happy it was mild case. It would just be nice to tell if it was the pox or not! I'm guessing it's too late now to have the doctor check it out. His next well child visit isn't until December, so I guess I'll have to wait until then to ask for a titer test.
