After a year of GI problems, I was given a Celiac blood test. This was negative. I continued to have stomach issues and terrible migraines. I also had a rash for several years that a Dermatologist thought looked like a Gluten rash. I decided to do an elimination diet and felt so much better after several weeks with no trigger foods. Immediately after adding gluten back to my diet I developed the rash again and the worst migraine of my life. I have been off Gluten for 6 months- no rash fewer headaches. I have been recently diagnosed and treated for Papillary Thyroid Cancer. When telling the doctor of my gluten sensitivity I was told with my negative blood test I do not have Celiacs. Is it possible that I can have Celiacs with a negative blood test? I know to get a positive Celiacs test I would have to go back on gluten. People tend to think I am just jumping on the Gluten free bandwagon because I do not have a Celiacs diagnosis. So frustrating!
