I’m allergic to corn.

I had chips at lunch and popcorn last night after dinner.

This morning I woke up and my hand was so sore, I couldn’t curl my fingers. (It’s some better now.)

I gained two pounds from what I ate, too.

So I now know that it is corn I am allergic to. (Remember I was wondering if it was corn or wheat?) I may have had a bit of wheat yesterday morning, but if I did it was far less than I usually have.
