This is perhaps one of the most painful affections to which the human body is liable. In most instances the pain is the only symptom; in some it is accompanied with marked constitutional or local ailment. The most general seat of neuralgic pain is in the head or face; but the fingers, the chest, the abdomen, etc., may any of them constitute its site. When the great nerve of the leg is affected with neuralgia, the disorder is known as Sciatica.
