Pattymelt Illness Duo - whataburger,

My girlfriend ordered a #5 Bacon and Cheese Whataburger. I ordered the whataburger pattymelt. Within hours I was having Diarrhea. The next morning the Diarrhea was very severe, my head was pounding, and my stomach felt like it was full of lava. I have to call in sick for work. My girlfriend also had a headache and nausea and vomiting. This lasted about 2 days for the both of us. | Symptoms: Diarrhea, Nausea, Fever, Headache
