Influenza generally doesn’t cause vomiting in adults. Maybe you had food poisoning or a norovirus. Hope you’re feeling better by now.
That’s what I’m thinking as well. Generally influenza symptoms are fever or feeling feverish/chills, cough, sore throat, runny or stuffy nose, respiratory congestion, muscle or body aches, headaches, fatigue. Some people may have vomiting and diarrhea, but this is more common in children than adults.
If someone comes down with stomach and intestinal symptoms without the other symptoms of influenza, it’s most likely a Norovirus or Norwalk or food poisoning. But either way, that’s no picnic, I hope you are feeling better too.
Although I will say that the last time I go the flu in the late 1990’s it hit me like a ton of bricks and very suddenly when I was at work; starting with the very sudden onset of nausea and vomiting, then by the time I got home a splitting headache, diarrhea, more nausea and vomiting, followed by coughing, sneezing, fever, chills, some more nausea and vomiting that continued for the next 24 hours, then really bad coughing, constant sneezing, a very sore throat, chest congestion and body aches like someone had beaten me with a two by four. I spent the next three days on the sofa under heavy blankets, so sick and miserable that 1) I didn’t want to keep my husband up all night and couldn’t sleep anyway 2) was too weak to want to go up a flight of steps to our bedroom 3) wanted to be closer to a bathroom and 4) wanted to be close to the refrigerator to get ice chips. I missed 5 days of work and the first day I ventured out of the house it was to go to the grocery store with my husband. I thought I was OK and feeling better, but soon was leaning on the grocery cart for support as I felt so weak, that I wouldn’t have been able to stand otherwise. That was about as sick as I’ve ever been with influenza excepting in the late 70’s when I was in high school and contracted the Russian Flu.
