When I came out of a two-hour knee surgery. It was exploratory to see if I needed a major knee surgery (I did), and when I woke up, I was in so much pain I literally went into shock - I remember waking up, then excruciating, mind-numbing pain, instantly being freezing cold and starting to shiver uncontrollably (which made the knee pain WORSE), and the nurses rushing me to the recovery room then covering me with blankets and constantly checking my temperature.
For my second knee surgery, they gave me an epidural beforehand.
That was before I was diagnosed with Ehlers-Danlos Syndrome, which can cause anesthesia not to work properly. I’ve actually had an anesthesiologist write a medical paper on me after I had a surgery. I’m guessing my reaction to anesthesia is odd, which is why time coming out of my first surgery was hell.
