Burger Sickness: Severe Symptoms - Five Guys, Dubai Dubai

Dubai, Dubai, United Arab Emirates

I had a little cheeseburger with lettuce onion mushrooms ketchup about 2-3 hours after violent nausea and vomiting, stomach pain, nausea, and headache all night long. The next day, diarrhea and nausea, completely loose stomach. It's the only thing I ate so there's no way it was due to anything other than this burger! My friend, who also had a burger, was also nauseous and vomiting. | Symptoms: Nausea, Diarrhea, Vomiting, Headache, Stomach Pain
