I swear... I used to be allergic to everything. And I mean EVERYTHING!
As I child I was allergic to dogs, cats, grass, trees, pollen, mold, ragweed, tomatoes, shellfish, peanuts, hazelnuts, any other nuts, and for a few months I was lactose intolerent. I'm sure there's other allergies too, but I don't remember them.
Man. It sucked.
Thankfully, I outgrew the food allergies. I am still a tad allergic to shellfish though. But it doesn't bother me to eat it.
But I'm still allergic to the environmental ones.
A few years ago, I started allergy shots. They inject like a form of your allergy into you or something. It really helps me. The only thing that sucks though, is that they can't do them for foods. Environmental only.
But I still have symptoms, occasionally. I was doing great all summer until just recently. This past week I've had a stuffy nose. My eyes itched really crazy one night. And I have eczema, so it's pretty easy to tell if something is bothering me. I'll get really itchy. And I have been crazy itchy this past week or two.
So I believe it's true.
