Oh I understand about cc in foods now. Scraping the gravy was like 4 years ago before I got onto this forum and learned a lot. I now take the same precautions a lot of supersensitives do except the shared household is probably the weak link. I may be non-celiac gluten intolerant based on the testing I have had done and the fact that my symptoms went away so fast even on an imperfect gluten-free diet. The only test that was positive was an 84 on an Igg blood test when normal is 30 or less. I think it is rare for true celiacs to recover so quickly due to the time it takes the intestines to heal. The return of symptoms 2 years into the diet is what I have been trying to figure out and deal with.
I see. Well, I do hope you find your "culprit" and get well once more! Best to you!
