Anybody get fever/headache after W2?

Not at all surprised that I caught something while in a swarm of people, but this past Wednesday (3 days after W2) I was hit with THE WORST HEADACHE OF MY LIFE and extreme chills/fever. I went to the ER because no medicine was helping. Ultimately, I tested negative for Covid and flu and was treated for a migraine and sent home.

So I figured maybe my body was just dehydrated and tired after the festival, but now, one week later, my poor boyfriend who didn’t attend has the exact same thing going on and I feel so bad!

Did anyone else experience this? Headache, chills, fever, and nausea were the only symptoms. It was so wild.
