allergist whom surprisingly diagnosed me with allergies to tree nuts, pitted fruits, and melon.
If you are truly
allergic to any or all of those foods, this diagnosis would NOT have come as a 'surprise' to you, given your diet.
What method did your physician use to diagnose your food allergies?
Please be aware that skin tests can yield false positives as much as 30-50% of the time, and blood tests, similarly, are only about 50% accurate in the absence of specific reaction history-- which you lack. You can't really eat an allergen without reacting to it on a semi-regular basis, or it's not something you're actually
allergic to, if you see what I mean.
For example: I am allergic to shellfish. I developed this allergy as an adult, out of the blue. I initially thought that I had "food poisoning" of some kind, which was really weird since I was the only person who got sick and everyone ate MORE shrimp than I had... but I was in such pain that I wanted to die, and at one point was afraid that I would.
I have never again
knowingly consumed shrimp. I have reacted to foods which were cross-contaminated with them, however, and I
know that I am allergic. Shrimp smells like death to me now.
Contrast that with another item that I once had reason to think I might be allergic to-- bananas. I broke out in hives once after eating a banana. I have no real idea why-- and it was a while before I was brave enough to test that one out by trying it again.
If I were "tested" for food allergies, however, heaven only knows what would turn up. As far as I'm aware, I
only have clinical allergies to crustaceans and citrus fruits, and it's possible that the latter is related instead to a pollen allergy... but I'm a highly atopic person. I'm guessing that I'd probably have ten or more "food allergies" that I don't actually have. If you see what I mean.
If you've been tested for EE and it's been ruled out, I'd be VERY suspicious that your food allergies are only false positives. Did you ever have any reason-- other than your attacks of pain fairly infrequently-- to think that you had allergies to those particular foods? ANY other kinds of symptoms? Do you happen to have a ragweed allergy, by any chance? (That one is associated with melon sensitivity at some times of the year, because the pollen is cross-reactive with some melons.) A birch pollen allergy? (Stone fruits such as peaches, pears, plums, cherries, and even apples are associated with that pollen in a cross-reactive manner, as are
almonds, at least rarely).
You might take a look at Oral Allergy Syndrome and see if that might explain your recent food allergy diagnoses, particularly if you have bad pollen allergies to birch and ragweed and were skin tested.
