I had one two years ago with a spinal anaesthetic. Was supposed to be GA but the anaesthetist was worried about my slightly runny nose in case I had a cold (I've since realised I have an annoyingly permanent runny nose, probably a slight allergy to one of my pets).
I was a bit alarmed as I was quite relaxed about a GA, didn't know what a spinal was, etc. Quick text to friend - it was what she had for her c section, it was fine. Anaesthetist talked me thru it.
It really was absolutely fine. It was having the spinal I was most worried about, and actually that was grand. A bit weird but not horrible, kind of funny too. Being wheeled into theatre was quite intimidating but everyone was very calm and kind. Consultant asked if I wanted him to talk thru what he was doing. I said yes but not to expect me to pay attention (awake but floating). Anaesthetist was by my side checking in on me.
Honestly didn't feel a thing. My legs were completely alien, I looked at them in the stirrups and couldn't relate to them at all 😂
Obviously a GA is different. I've not had one for awhile but they usually ask you to count backwards from 10 and you're out by 7. You're a bit loopy coming round (aged 13, I constantly asked what time it was as I couldn't belive it had been so quick). Possibly some nausea.
Recovery time is different. Those who had GA were able to go home much sooner than I was, and advised not to drive for 48hrs. I had to wait until I could walk again (several hours) but was OK to drive the next day.
