Yours sounds like classic food poisoning..
We all had fever, sore lungs, cough, chills, sore throat, aches & stiffness to varying degrees. One is mid-30’s runner, high altitude hike/camper, the other is late 30’s daily gym attender, benches 3 multiples of his weight, and me, old, fat and lazy.
It got us all differently. I thought I was going to be the ambulance driver a couple of times.
