My 14 y/o daughter has been sick for several years. She is very athletic, in great physical shape but catches every bug out there. This year the stomach pains started and never went away. ER trip after playing catcher left her not being able to breathe. Finally have a celiac test come back positive. We started the gluten free diet about 1 week ago and she is suffering from severe headaches, blurred vision, joint and muscle aches, fatigue etc. Are these symptoms normal when going off of gluten? Should I be tempering off the gluten instead of having her go cold turkey? Any advice would be appreciated!!
