My son started breaking out in a rash some of it was really raised and the rest just migrated around his body with a lacey almost design-like appearance...the doctor showed us some photos and said it was fifth's disease...now...my other son and I after being in the sun are starting to get rashes that come and go...I am freakied out to the point of tears...I am a clean individual who takes very good care of my kids i don't know what to do and the doctors look at me like I'm fanatical...what should I do and what could this be from...
