I got a call from a mother 9 weeks postpartum who was sent to a doctor for symptoms of fatigue. Her employer was concerned because she seemed to be tired all the time. The doc told her she needed a pacemaker and would have to wean 48 hours before surgery because the milk in her breast would shortcircuit the pacemaker. I kept a straight face and suggested a second opinion. She got a second opinion who told her that her heart was fine. She went back to the first person, had the surgery, and was still tired afterward. I swear I am not making this up - I still have my log book notes from it!
