For me, it was 40 years ago, when I was an Army medical officer, providing primary care for 2,000 soldiers, including one who kept popping up repeatedly as an emergency admission to more than 15 military and civilian hospitals throughout Europe. During that two year period, his complaints were always the same: unbearable abdominal pain and hematuria. This patient confounded medical personnel, clogged administrative systems, and challenged the Army’s best legal talent. Relentless sleuthing eventually revealed that his hematuria was self-induced: he was surreptitiously using a hat pin to traumatize his proximal urethra.
