Food Allergies Treatment

I love shrimp, lobster, and crab.

But the 2 times (first on purpose, then on accident) that I had scallops, it was followed by 24 hours of excrutiating pain – vomiting, diarhea, cramps, and I literally could not get out of bed unless I was lying next to the toilet.

What could explain this? Someone once mentioned something about mercury or something, but I don’t buy it. And should I stay away from
foods like clams and oysters because of such an adverse reaction to scallops?

Thanks!

My grandson has a severe food allergy to tree nuts (not peanuts). Many cake mixes, snack products, and prepared foods are made on equipment which also processes nuts. We cannot use those products. Can anyone with similar experience suggest some prepared snacks or mixes that are safe?
He would go into shock and having breathing difficulties which could threaten his life. It is very dangerous!

Just curious if anyone has had an all nut and all seafood food allergy develop later in life? If so, how and to what? Thanks.

My son is 4 and a picky eater, since he has an allergy to wheat, soy and milk, the healthier things I could get him to eat, he can’t have. I need some sweet recipes along with regular everyday meals that he thinks taste just like what he’d like to eat. Such as mac n cheese, cookies, or pancakes.
