I recently had a cookout/barbecue that spanned for two days over the Memorial Day weekend. During the cookout, we had crabs, shrimp, red wine, pineapple juice (w/ rum), sausages, meats...all kinds of food. At the end of the second day, I slowly started to break out in hives. By nighttime, I was covered in hives. I took Benadryl during the night. Only to wake up lightheaded and pass out on the floor. (I didn't lose consciousness). My husband called 911 and I went to the ER and was given EpiPen shot and steroids. A week later I was allergy tested and tested negative for all foods but very high for trees, grass, weeds.

So after a week of not eating much because I thought I had developed an allergy to crabs, I began to eat regular again and had a few drinks during the week. By the end of the week, the hives came back. They grew worse over 3 days even with taking Atarax. I woke up with a swollen eye and lip and ended up back in the ER. Same thing again.

This was 2 weeks ago, I'm taking one Zyrtec daily and haven't had hives since. My doctor is baffled. My Allergist wants me to come back in but suspects it's Ideopathic Uticaria. I can't accept that. There has to be a cause.

So...my question is could the holiday weekend have caused my histamine levels to overload my system? Since I didn't know I had an allergy to trees and grass, my body must have been producing histamine due to the amount of time I was in the grass. Then eating/drinking high histamine foods may have worsened it.

Does this make sense?

You should go back to the allergy doctor and talk about getting retested for some of those foods, or more specific allergy testing. Shell fish allergies could still be a possibility...and get an epi pen to keep with you at all times and keep benadryl handy for an emergency...
I think you tested negative for those is because you still had the steroids in your system allergy testing needs to be done about 3-6 weeks after taking antihistamines and steroids and I really think this allergist tested you too soon after your reactions...you can look up How to prepared for allergy testing on google, but I think it was done too soon after your reaction.
others will come by with better advise...
Many well wishes and keep us posted as we do care...

Thanks for your input! I did also have a blood test which confirmed the skin test results.

I also didn't react immediately either time. It happened hours later after eating or drinking.

I go back next week so we'll see.

You should google "how to prepare for allergy testing" at my last clinic they gave me a listing of medications and the time frame to be off them for more accurate test results, so your testing could've been flawed, because of the antihistamines in your system at the time.
and if in your gut you do not agree with the "ideopathic Uticaria" then believe it and push for another answer...
Do keep us posted about your doctor visit next week

Delayed reactivity does not show up on the traditional allergy tests (those tests only look for IgE antibody-mediated allergies)...suggest consulting an Integrative or Naturopathic Physician to test for IgG/IgA/IgM antibodies to foods. And make sure they do a total immuneglobulan panel as well (i.e., total IgG, total IgM, total IgA, total IgE), in case you have a deficiency that would affect the test results.

Yes, it is possible your high-histamine foods combined with the pollen allergies to create an "allergic overload." And some foods cross-react with pollens (especially some fruits/veggies & grains), too.

I agree your testing was done too close to taking antihistamines & steroids. It takes about a month for the Zyrtec type of antihistamine to fully exit the body (Benadryl takes about a week), and up to 6-12 months for steroids to exit the body.

Thanks. I went a couple of months with pretty much no problems. I did notice when I ate certain things my throat felt tight. This week I ate a burritto and my throat felt really tight and I realized it was swelling. Back to the ER. My allergist doesn't think I would have developed a new allergy at my age (36) but I asked to be tested for avocado. The common ingredients in all my episodes have been avocado (guacomole) or fruit juice.

My regular doc is ordering other tests on my throat but she suspects it's an allergy.

I think it is boiling down to OAS (oral allergy syndrome) and I'm having cross reactions due to my pollen allergies.

Fun.
