I know nothing about
Humira..sorry. Were you on a med before? Many meds do contain gluten and they say each time you get a refill, you should call and question the lab.
Do you eat "gluten free" processed foods? Or corn, rice, oats...any grains? Often times these still contain gluten by cross contamination and also, some of us can't have any type of gluten, not just the type from wheat, rye, and barley. All grains contain some sort of gluten and many of us are much better off without any grains, even the ones they tell us are safe and not necessarily grains like buckwheat, quinoa, and such.
Have you checked into other intolerances? Many of us also have many, many intolerances like nightshades, cruciferous veggies, shellfish, histamine...the list is long.
Feel free to email me at [email protected] I answer any questions I can.
