Psychological conflict has been understood by researches as a cause. Other possible causal factors include a medical ailment, a dissociative disorder (characterized by unintentionally escaping from reality) and/or a personality disorder in which the person is not able to manage their behaviors and emotions appropriately in a situation. Furthermore, these symptoms manifest after a distressing experience in life.
People with this disorder do not try to conjure up these symptoms just to gain shelter; they do not do this just because they want personal gains neither are they purposefully injuring themselves or falsely reporting their symptoms in order to become a patient. Unfortunately, a proportion of the health care providers think that this disorder is not a valid ailment and they tend to tell their clients that they have made up the problem. However, it should be understood that this is a real, distressful condition. People cannot just switch it on or off as they please.
The physical symptoms arise, as researchers believe, in order to help the person cope with the conflict inside. Like in a person’s case who does not feel that violent feelings are acceptable, that person starts to feel numbness in their limbs following anger. So, instead of feeling the intense anger, the person felt numb in her limbs.
