I have a complex digestive system disorder, so for various reasons, I've not eaten tomatoes (and other foods) for a few years. As my health has improved, I've recently reintroduced raw tomatoes. I've been breaking out in welts/hives/rashes. I've experimented and I'm 99.9% sure it's the tomatoes.
How do I know if it's an allergy or an intolerance? Would it be silly to keep testing my theory? And for my final question - should I be eating tomato sauce or cooked tomatoes if raw toms disagree with me?
Thanks in advance.
