I'm now 50+ years old & I've never had any type of allergies in my entire life (not even seasonal outdoor-related).
But (pun intended!), within the last couple of months, everytime I eat any type of whole nut (not in a "butter" form or as a "small" ingredient in something else), in exactly 12 hours, I develop a terrible, bright red rash around my anus. Like a 3" circle of very uncomfortable burning & itching. It is awful (murder to wipe)!
It lasts a day and then stops.
I've been careful to see if it does the same with tomatoes (nope) or potatoes (nope). Nada for any other type of usual allergens.
Only whole nuts. Peanuts are the worst (oh, the discomfort after eating a mini Snickers & 2 mini Mr. Goodbar from ds's Halloween haul!), with pecans and almonds a close second. Haven't tried walnuts (I'm being cowardly!).
Like I said, any type of processing seems to change the nut, so no pain with nuts in form other than whole (I love cashew butter, no problems, thank goodness).
I know it is easy to avoid whole nuts, it's not a big deal. I was just wondering if anyone else has had this type of reaction, especially as an adult with no history of any kind of allergies!
