I’ve had several surgeries, and maybe 6-12 procedures where anesthesia or partial anesthesia was used.
Each time, I felt like it took 6 months to a year to come totally out of the fog!
I’ve noted that people (about 65 & older) in my large extended family often have difficulties after their surgeries… just a bit off.
And have noted that in 80+ people, a surgery often seems to bring on a decline they don’t recover from.
Just on principle, many of us have worked to not have another surgery!
