Strangest Food Reaction yet...

Yesterday my daughter and her boyfriend stopped by my workplace to have lunch with me. They wanted to go to Portillo's (a Chicago Hotdog place with a location in AZ). I LOVE Portillo's! Well, I should say my heart loves Portillo's but my stomach doesn't.
So, i contemplated what to have, knowing darn well that I really shouldn't eat any of it (full of gluten, dairy, soy etc). Welllllll......... I had a craving for a cheeseburger! I'm not currently eating red meat and I haven't had a cheeseburger in 2 years.

So i ordered a plain cheeseburger and a small fry. That's it.
I ate and enjoyed EVERY single bite.

Wonderfully charbroiled......perfect.

Then we headed back to the office...... I could already feel rumblings and feel the bloating starting. I expected that.
But then about an hour later I felt like I had HIT A WALL. I mean, seriously, it took great effort to even keep my eye lids open. It was SO strange. AND.......then I started having these unexplainable emotions, like I was going to cry! My eyes would well up with tears......it was the strangest thing.
I felt horrible.
Eventually, I went home and immediately laid down. I napped for a little bit and around 10pm I got up to join my daughter in some TV watching. All of a sudden my legs started to tingle, my ankles started to burn and I knew what was happening......
HIVES !!!!!! Oh no!!!!! I resisted the urge to scratch, but that tingling and burning feeling is horrible! I sprayed some Bactine on (I don't know why...it never helps! lol).
Eventually I went to bed and I felt much better this morning with only a few hives left.

My daughter felt compelled to give me the following advice:
"Mom, i don't think you should eat Portillo's cheeseburgers again."

Gee, thanks honey.......I think I figured that out already.
