The suddenness with which the buzz has expired is alarming. The drugs used last Wednesday at the Perth & Smith Falls Hospital during the brutal surgery on my left knee replacement have finally worn off. At the same time the post-operative miscellany with which the hospital staff adorned me upon my gleeful withdrawal from the clinic has acquired a new-found relevance. I have spent the past hour walking up and down the apartment buiding hallway, lying upon the bed while repeatedly raising my left and right leg, bending my toes on both legs forwards and backwards, compressing my buttocks for 30-second intervals then releasing, stretching my legs while sitting. My entire universe is for the moment comprised of varying degrees of leg extremities and pressures. I never imagined that pain had such a utilitarian and therefore inarguable partiality!
