I had allergy testing as a child. As far as I was concerned, I was allergic to everything (everything I LIKED, anyway!) - cats, milk, chocolate, pine trees, grass, lots of stuff.

You asked about the testing. They used a block of fine tiny needles, and just poke on your arm or back. You really don't feel it, less even than a pin prick I think mine was 5 across and 5 down.

Then you go sit in the waiting room for 10 minutes, and return for the doc to look. And "poke" which swelled up like a mosquito bite, means you are allergic to that item. Like a mosquito bite - as I recall, they didn't itch or anything, it was just the visual thing.

Since our allergies change every 7 years (no idea where I read that!), I am sure I am allergic to a whole different slew o GOOD stuff now, lol.

I take Claritin and Benadryl - this one puts me to sleep so I use that at night.

I hope you identify the trigger soon; when it impacts your breathing, this is a HUGE issue!
