I have been suffering from IBS for years and I can't go a week without having at least two migraines. Do you think I have food allergies?
I agree with Tracyole. too much of a cooincidence really.
I get migraine triggered by chocolate
My mother's food trigger was cheese (especially if eaten in the evening).
Why not try eliminating gluten (all flour products; bread; instant sauces) for a week or too and see if you improve? There is now a very reliable blood test for coeliac disease, it might be worth getting it done
