Nevermind the fact that even if it is forgotten, an awake mind will suffer greatly in the moment - pretending that suffering did not occur because it was forgotten is some next level self-deception.
I don't think most surgical patients are concerned with the kind of trauma their cells or gut microbiome sustain during surgery. In fact, if these systems recollected zero trauma it's doubtful the surgical outcome would be positive. When most people discuss suffering they are usually discussing the suffering of their selves. The self requires coordinated effort from the brain. When surgery occurs, it could be well argued you would want to use the least anesthesia necessary to avoid the kind of suffering the patient wants to avoid.
What are you actually on about? Why be purposefully insulting?
If there's no suffering in the now, then how can one remember that one suffered?
One can remember that one suffered because one can experience pain in the now and bridge that into a context where the self exists. Selfing is the trick of consciousness, it's not necessarily the natural state of all creatures with sensory equipment or memory - it's an additional trick that only a handful of creatures have.
