“I’m just so tired all the time. What can I do, doc?” Fatigue is one of the most common and challenging problems faced by those of us in clinical medicine.
Not only is it a vague symptom, but the number of possible causes listed in medical textbooks runs literally into the hundreds, some quite serious. With a differential diagnosis list that long, I know that as a doctor, I almost instantly start to feel fatigued myself when I hear the complaint of fatigue. It is exhausting to consider and to address comprehensively.
