Hi Pennodream,
My doctor wanted me to try a gluten-free diet to see if it had any effect on my facial pain/headaches. It was all very confusing for about two weeks, but I wanted to let you know that it hasn't been bad at all. It just takes some getting used to. I don't feel like I'm starving or missing out on anything. I've been finding new recipes and I feel that my diet is a lot healthier than it used to be.
If you're going to have a biopsy, don't go gluten free until after the procedure or it will alter the results.
Good luck with everything, Cheryl
