I’ve been allergic to shellfish all my life and I always have the same exact reaction.  No, hives, no swelling, itc.  I just get really really itchy, red, and nauseous. 

I’m really bad though because I LOVE crabs, so I put up with the symptoms and eat it anyways so it’s not THAT bad.

I imagine it’s possible crab could bother you but not shrimp–maybe that’s why you didn’t have a severe reaction to it?

@bestbuddies: My friend was actually diagnosed by his doctor. Otherwise he probably would have never known since he eats that on a regular basis.

oh that stinks .. my dad ate shellfish his whole life .. and then at 23 had crabs, which he had before…. he wound up on life support in the ICU in the hospital in NYC.  He’d grown up eating mussels, crabs, & shrimp.  He hasn’t had it since.  It was THAT fast.   

 ***edit… i have a friend that developed the same thing … and as long as she washes the shell off …. she can eat it .. it’s the mercury she’s sensitve too.  good luck

im allergic to everything! and the older i get the more i get allergic to.

when i was about 7 i found out i was allergic to shellfish, but could still eat regular fish, it wasnt until about 3 years ago iw as at a wedding, took a bite of salmon, and almost died (thank you benadryl) went back and got tested and surprise im NOW allergic to ALL fish, practically anything out of the ocean.

i have similar stories about peanuts, different fruits, and raw veggies.

i have taken to keeping benadryl with me at all times just in case, i have an epipen as well. it sucks.

my suggestion is to go to an allergist and get tested. its sucks – itches like crazy but at least you know for now. i get tested every 2 years or so.

I am allergic to crab…but somehow not to lobster or things like mussels/clams. The one and only time I ever ate crab my lips, tongue, and throat swelled up and I had to be taken to the ER. For some odd reason, though, I don’t seem to have any problems with other kinds of oceanic critters. One of my friends said it could be something to do with the high iodine content in some kinds of shellfish, but I’m not really sure what the root cause is. All I know is that I am too terrified to ever touch crab again, which doesn’t make me the most popular customer at sushi restaurants (I have to ask the staff to please be sure no crab touches my food, because I’ve definitely left restaurants with lips swollen so bad I had broken blood vessels that looked like a purple mustache…not so hot!).

I also have a friend with an allergy to shrimp who has no problems with hives or swelling, but she gets that nauseous/itchy feeling. I don’t think she’s ever had her allergy “verified,” but if you have a sure sensitivity to something, mild or not, be careful when you eat out or purchase packaged foods (it’s surprising the number of things that have unnamed “shellfish” in them, like vitamins!). If you’re worried about a more serious reaction – which I think can happen when you get repeated exposure to an allergan – I would definitely see your doc or an allergist to have an allergy battery run.
