It’s probably just cotton fever. I’ve had cotton fever for 12 hours before. I once shot up using sink water out of a motel sink.. to tell you I was violently shaking for 8 hours wishing to die would be an understatement. My girl kept asking if I was coming to bed to find me on the floor rocking back and forth
Key sepsis signs - fever or chills, extreme cold / low body temp, mental confusion / disorientation, fast heart beat, clammy / sweats
I don’t believe sepsis would develop that quickly or show symptoms that early.
Pray you don’t have sepsis cause if you do as you don’t die it’s a weeks long hospital trip, and a long road to recovery
