I had a GA for both of my knees. I do not want a spinal--ever---it is just too creepy to have a needle in my spine--which is one of my parts that works pretty well.
I woke up in recovery--no nausea, no sore throat. I went back to my room and got up in about 2 hours to go to the bathroom. I was just fine---after I went to the bathroom, I changed my clothes since I did not want to wear a hospital gown and put on yoga pants and shirt. Got back in bed (Had to climb over the cpm).
When the nurse came in, she said I should have called her--but frankly, it never occurred to me to call anyone--I just had to get up and move around.
With my second GA --no effects at all. I asked the doc for something to prevent nausea and I guess it worked since I did not have any. I woke up in recovery and was in my room visiting with friends in an hour or so.
I am 69 and the only time I had any reactions it was to Versed which is what they give you for a spinal---I had memory loss for two days. But, I recovered and am fairly sane too.
