Allergic to tomatoes...kind of?

I can eat raw tomatoes just fine...but once you cook them, I can't have them. If I eat them my throat starts to swell shut. I have the same problem with ketchup and tomato sauce (once again, cooked tomatoes, I'm sure).

What does cooking do to the tomatoes? It has to be something that's released when you cook them that I'm allergic to, does anyone know what it is or have a similar problem?

Update:

I've had 3 of those done before for various things because I have severe allergies. I don't really want to get a food test done, I've been seeing a pyschiatrist ever since I started my immunotherapy and I'm afraid I'll have to start back at the beginning if I have more allergies to be afraid of. And I've never been allergic to raw tomatoes at any time in my life, just cooked ones.

    I honestly have no idea but after looking up the difference between the two.

    I found this:

    http://www.vegsource.com/harris/raw_vs_cooked.htm

    Cooking is a form of predigestion in which heat is used to hydrolyze nutrients which would otherwise be hydrolyzed at body temperature by digestive enzymes. The end result is the same, but one raw food author seems to obliquely suggest that another reason for leaving food enzymes intact is so they can be absorbed intact into the blood stream to continue their digestive work there. Such a process would be catastrophic as the absorbed enzymes would be peptide fragments and would be more likely to generate allergic and autoimmune reactions than robust good health.

    I think it has to do with the nature of heating up the chemical bonds and the protein structure is altered. I admit i was too lazy to read this article but I think it has your answer:

    Oh I found this too:

    Many of those allergic to tomatoes are sensitive to the IgE protein in raw tomatoes, which is sometimes destroyed when tomatoes are cooked.

    That might explain it.

    Hope this helps!!

    Cooking the tomatoes does not change them in any way, in terms of what they are made up of. However, it's very common to see people allergic to raw tomatoes in the beginning and then later the allergy develops further and includes cooked tomatoes and tomato paste. The tomato allergy is not caused by the tomato itself, but instead by a type of protein found in the tomato plant. Because of this, you may also become allergic to potatoes, eggplant, tobacco, and foxglove over time.

    Tomato allergies are really rare in general, but when they do occur, they are caused by the seeds, skin, and juice of the tomato most frequently. I urge you to have a skin prick allergy test to determine if it is in fact tomatoes that you are allergic to. Generally when people have food allergies they are allergic to multiple foods, and seeing an allergist now can avoid a lot of suffering for you in the future.

    Surely not ALL the parts: Imagination & Creativity go a long way towards avoiding those sort of problems. Besides, pregnancy isn't actually considered to be an allergy...
