Grilled Chicken Sandwich Illness - Whataburger, San Antonio Texas

13900 O'Connor Road, San Antonio, 78233 Texas, United States

I went through drive-through, and ordered a grilled chicken sandwich for me and a kids cheeseburger, and some shakes late at night and in the morning me and my child woke up with horrible symptoms. I let a full 24 hours go by to see if it was just something small. My child feels fine but then again he only took two bites. I ate the whole burger and I feel horrible and this is day 2. I gave a shake to my friend, but their stomach does not hurt at all so that's how I know. It was the food and that's the only meal I ate that day as I do not have a big appetite. | Symptoms: Nausea, Diarrhea, Stomach Pain, Cramps, Chills, Headache
