Update: Last night he called me into his room to tell me his back was itchy. He had a massive rash and hives all over his body! Gave him some benedryl and oatmeal bath and lotion, and today the hives and rash are pretty much gone. Taking him to the doctor's in an hour. Must be an allergic reaction to strawberries or watermelon. Poor boy, nobody every gets allergic to broccoli, do they? It is always the good stuff!
