Fast Food Illness Mystery - In-N-Out Burger or McDonald's, Encinitas California

130 Calle Magdalena, Encinitas, 92024 California, United States

I'm not sure if it was Double double burger from In-N-Out in Encinitas or it could have been a McDouble from McDonald's at Nobel and Genesee, UTC. All I know is I had a very sharp stomach pain that felt like an internal stabbing then vomit and diarrhea since 12 a.m. | Symptoms: Diarrhea, Fever, Nausea, Vomiting, Stomach Pain
