Pain, breathlessness, bleeding, deranged vital signs and the acute inability to either walk or talk usually mandate immediate hospital admission. All these presentations are associated with a relatively small number of possible diagnoses and are often managed by specific protocols. There are also a large number of other complaints and nonspecific presentations, which often remain medically unexplained, that may prompt hospitalization [1]. These presentations include generalized weakness and fatigue, which are among the most frequently reported complaints in emergency care [2,3], diaphoresis, dizzy spells, “funny feelings”, light headedness and many others.
