Hysteria in Siddha Medicine
It is one of a psychiatric aspects, of much importance since it's prevalence is increasing now a days. This disorder should be clearly understood by the doctor and the relatives of the patient as well, because the symptoms shown by the patient may create an atmosphere of tension around and the physician may misinterpret these symptoms.
Hysteria, in its colloquial use, describes unmanageable emotional excesses. People who are "hysterical" often lose self-control due to an overwhelming fear that may be caused by multiple events in one's past that involved some sort of severe conflict; the fear can be centered on a body part, or, most commonly, on an imagined problem with that body part.
