Oatmeal...gluten

We have this wonderful baked oatmeal recipe that everyone loves.  Today, tired of eggs and fruit, I whipped it up. 
I had read that there is debate weather you can eat oatmeal or not if you are gluten intolerant because oatmeal is genetically different..bla bla bla. 
The baked yummy goodness was warm and terrific going down the hatch.  It really tastes like a cookie because of the sugar, walnuts, and cranberries in the recipe.
I was taking my last bites when I felt that feeling.  Nausea.  My throat felt tight and my tummy was not happy.  Trying to ignore the feeling I went about my business of kids and home.  About thirty minutes later I was running to the bathroom.  I felt a little better afterwards but then another wave hit and was on the run again. 
I don't think there is any left in me, but my throat is sticky and feels tight and I have that heavy head feeling. 
In conclusion:  Oatmeal is not ok.
