Dd has a rash on her arms and legs. It started with a few patches on her thighs and wrist. Now she has little bumps on her arms, and the upper part of her legs, plus a tiny patch on one cheek. They are small, raised bumps, only slightly pinker than her skins--like little pimples, but no white dot in the center. She's very mildly itchy. At first we thought it was an allergic reaction, because she had quite severe food allergies, but Benadryl hasn't done anything.
It's not fifth disease, which she already had (and didn't look like this). It doesn't look anything like Coxsackie and she seems too old for roseola. She's been vaccinated against chickenpox--which wouldn't offer 100% protection, of course--but with no bumps at all on her torso/back/neck and no other symptoms, I don't know if it chickenpox fits the bill anyway. She has no fever, malaise, etc. so I'm disinclined to drag her to the doctor unless things get worse, but I'm racking my brain to figure out what it is.
