Hi! My 19 year old daughter was diagnosed with Celiac Disease this past May. She is completely gluten free and was feeling good until a cross contamination in November. For the past three weeks she has been having headaches and they get worse after she eats. She is so on top of her eating and we know it’s not caused by gluten. Doctor said to take magnesium and vitamin B12 supplements but nothing is helping. Has anyone had this issue or have suggestions? It breaks my heart she feels so yucky!
