Dust Mites.
Cats, dust mites, ragweed, pigweed, a few trees, I think. Those prick tests are not fun!! My worst trigger is our filthy office, they never dust in there, no matter how many times I complain. I don’t sneeze at home, even with the cats.
I take OTC Claritin, Singulair, and have Omnaris and an albuterol inhaler. Fun times!
I’m violently allergic to shellfish of all kinds. It took quite a few years for my mother to figure out that I was not just vomiting all night every time she fed me seafood as a form of defiance. Because of that repeated exposure and inevitable violent response, I can’t eat fish, either. I doubt I’m allergic to it, but the odor is similar enough that my throat closes. I’m also allergic to nickel and apparently to aloe vera.
There’s this dye you have to drink when you have some sort of scan of your upper GI when they’re looking for an ulcer.
Whatever that stuff is, I’m allergic to it.
Good thing for me is that you’re only going to get it in a hospital, so when I found out I was allergic to it, I was in a hospital.
Penicillin. It causes a sensitivity to artificial colors (e.g. fruit punch) which causes hives.
edit: Including bread mold.
Cats and pollen. And we have 2 cats.
No more. My only known allergy is to Mr. Bubble.
Cats, pineapples and beans.
Can you guys tell me the costs of getting “the works” in an allergy testing clinic? I’m allergic to something, I just know it. Except that I don’t actually know it so I need the tests to show what it is. Obviously I am without any sort of health insurance or else I wouldn’t even be asking. If it’s cheap enough I’ll spring to have some closure on just what the hell is making my eyes look like I’m a huge stoner.
Latex. And this thread is another reminder that I need a medic alert bracelet about that, because the worst time to have an allergic reaction to latex is the time when I’m most likely to be surrounded by it and unable to tell anyone – in an ER.
Wheat.
Except that it’s not exactly an allergy. It’s an intolerance.
I could, for instance, stuff wheat up my nose or dance naked in a wheat field without any problem.
If I eat any, that’s when things get bad. There’s apparently some weird thing with gluten where it can cross my intestinal wall intact, and then it picks fights with my immune system. The results have been abdominal pain, diarrhea, migraines, joint pain, asthma, depression, and ADD. Oh, and hay fever. Once I stopped eating wheat, all those things got better. Weird.
I’m almost completely the opposite. Had the full allergy test a couple years ago and found the prawns and lobster were fine, other shellfish I had a mild reaction to, and fish I’m outrageously allergic to (had always just avoided seafood in general, was good to know that shrimp/prawn/lobster are safe).*
Also most all of the grass/dust ones.
*On that note, if anyone with fish allergies goes to Cambodia, do not order the ‘Beef with cheese cambodian-style’… when they say ‘cheese’ THEY MEAN FISH PASTE…not fun finding that one out 
Penicillin here as well. I’ve been told my whole life about this horror story from when I was 2 or 3 and was prescribed some for an infection and “almost died.” But then I was recently mistakenly prescribed some medication derived from Penicillin and nothing happened. Weird?
Like kidneyfailure, I’ve been told about an incident when I was very young that involved penicillin during which I was violently sick and very close to being hospitalised. Since then, I’m pretty sure I’ve had amoxycillin at least once without any significant side effects, but I am not tempted to try penicillin while there are other alternatives I could use.
The down-side is that last time I had a nasty ear infection that went straight into the bone, penicillin would have sorted it out very easily but since I can’t take it, I ended up spending a few days in hospital having IV clindamycin instead. Not fun, I can assure you.
I don’t have allergies to the ‘normal’ stuff, although I do find that lactose irritates my skin somewhat so I have to be careful not to have too much dairy stuff, and I stick to lactose-free milk to minimise the reaction.
I’m allergic to some sort of pollen. It’s not horrible, but it is uncomfortable. Since I don’t go outside much anyway, it’s not hard to avoid.
I’m also allergic to Augmentin, but thanks to that, I can’t have any penicillins. Interestingly, I’m not allergic to any of the cephalosporins, which makes things easier when I need antibiotics.
I’ve had the full testing and only reacted severely to dust mites. I had already known I was allergic since cleaning and exposure to dust sends me into major allergic attacks. I had very mild reactions to chocolate and sesame, never giving up chocolate, no way, no how. Anyway, I’ve never noticed any problem with chocolate and I probably couldn’t eat enough sesame to have a reaction.
I thought I would be allergic to some pollens since I have seasonal allergy symptoms, especially Punk trees which sent me into asthma attacks before I was ever diagnosed with asthma. My allergist said that I am not allergic to these things but they are irritants that cause allergic like reactions and Punk trees are one of the worst irritants. Some genius thought it would be great to plants these invasive stinky trees all over Florida. Fortunately, being on Zyrtec and Singulair all the time has lessened my “allergic” reactions, except for dust which still causes problems and I usually have to take a third antihistamine if I’m around it a lot.
I’m also allergic or sensitive to codeine. Within 30 minutes of taking it I get painful stomach cramps and puke my guts up. Fun.
Cat dander. Big time too. If I’m in a house that harbors a cat (or even near a cat owner wearing exposed clothes) then my asthma will flare up in a bad way, and the symptoms can last for days. Days.
Not good.
It’s called coeliac disease.
Sulfa.
I once had an infection and had to take it. I broke out almost immediately. My dad said, “That’s funny, I’m allergic to sulfa.” Later, I was talking to my mom (who lived 600 miles away) and she said, “That’s funny, I’m allergic to sulfa.”
Information that would have been useful…
28 different pollens, including juniper and eucalyptus
cats
mice
dust
mold
penicillin
almond oil
lanolin (which means wool, cashmere, angora, etc., as well as skin lotions containing lanolin)
ramie (a Chinese grass often blended with cotton in clothing)
Yesterday I walked by a eucalyptus tree and within seconds I was sneezing uncontrollably. I’m also one of the few people I know who prefers articificial fabrics to natural ones (except for cotton). Give me some nice rayon or polyester, at least I won’t itch. I once tore the neck of a sweater because I was scratching so furiously – it turned out to be a ramie blend.
