My 9 yr old son has just been diagnosed,( blood and saliva tests only).We've been wheat free for i month and also gluten free for 1 week. He's been having horrible nightmares and really bad headaches for the last 4 days. Is it possible his body is detoxing? Also a red scaly rash on the backs of his arms and elbows seem to have appearred. Any ideas/advice anyone. This is so new new to us and a little scary. Please help.
