B says the muscle spasms intensity has been reduced quite a bit. Instead of his legs & feet having a mind of their own, he'll just notice a muscle tightening and loosening... like when guys want to show off a bicep muscle. Important detail is that he only has real feeling in his legs and feet, to about mid-thigh.
Also, I'm having a hard time getting Hol to accept a basic fact of how morphine pumps work. There isn't any psychotropic effect per se; it's directed into the spinal column to soothe the nerves that are agitated & read by the brain as pain.
It is really amazing how positively this small change has helped. He's working at building up his stamina, strength & muscle again by cutting up some downed trees & splitting firewood (for next year). It is repetitive, and I have a wood splitter, so it's not like he's swinging an axe but he put in close to 8 hrs yesterday - with breaks.
Every thing about his presence is clearer and brighter. That is a total relief.
