Allergy free? A builidng paranoia

For the past 6 months I've had mysterious skin conditions arise, and countless sore throats. I thought it was a rash, strep, glandular. As I sit here with an itchy throat (I didn't know throats could itch like that) that I'm pretty sure is swelling shut after I ate a bag of almonds, I know I really need to get an allergy test.

But I've never had allergies. Well, once, 9 years ago I had a reaction to something that was blooming one day. My face exploded as I stepped out of my apartment on beautiful May day. By the time I walked the two blocks to the T my nose was running, eyes swelling, and I was coughing. Once I washed my face and took a Benedryl I was fine, and the next day whatever was blooming must have been done because it never happened again.

Not only have I never had allergies, but I come from a family of long time allergy sufferers and have been proud of my non-allergy status. Everyone else carries allergy medication with them or is on prescription stuff. I was free to sniff flowers, eat strawberries, and enjoy other mundane things without thought. But now, well...since I have no idea what I'm allergic to, everything is done with unease.

Here is a list of things I'm potentially allergic to:
Almonds--throat irritant. Maybe life threatening if my throat closes up.
Mango--lip and mouth reaction. Maybe life threatening if my throat closes up.
Cherries--lip and mouth reaction.
Wheat--possible skin irritant; have had throat swelling after drinking Hefeweizen . Maybe life threatening if my throat closes up.
Cilantro--taste like razors. I hate this herb. It has wrecked many burritos for me. I'm sure if I ate a lot of it my mouth would swell.

So, pretty much most of these have the potential to kill me. Nonetheless, I eat almonds and cherries alot (I think the cherry and mango overlapped and want to believe it's just mango that my body had a problem with), and wheat is in everything.

My main issue with these developments is two fold. The first is that they developed very suddenly. In the past two years my body has been through a lot with my pregnancy and subsequent "total body recovery program" I've been trying to maintain. I lucked out in having a wonderful pregnancy...happy, healthy, normal. So now my body decides to be all f-ed up? It's probably the hormones, blood pressure fluctuations, and general chemistry change that happens, but that leads me to point two. What is next?

Am I doomed to continue to develop weird conditions as I age? Isn't aging enough? I am the only person in my family who can wear contact lenses...will that change too? Is it allergy related? I have foot pain now, and although I'm a runner, I'm convinced it's hereditary. Will I need surgeries like my aunts?

This building paranoia about my body chemistry is new to me and unsettling. I guess I better call for an allergy test.
