There is a long hallway on the backside of St. Joe Hospital’s Reichert Health Center. It runs like a tunnel to various rear sections of the medical center complex at St. Joe’s: there is Pain Institute just inside to the right of the wide sliding doors that whoosh efficiently and quietly aside as patients walk or roll in on wheel chairs. If you go straight and then left you enter the broad main lobby of Reichert, which pulses with the comings and goings of the ill and relatives and doctors and nurses throughout the day.
