My daughter 25 her body become stiff and numb after dhe got angry about her work.her face become pale.is it because of tension?or what is it?

Need more info: Did she become nauseated? Did she feel faint? Did she have have involuntary movements? It's hard to say what happened. My guess would be a neurological reflex called a "vagal response." you can read more about it here: http://en.Wikipedia.Org/wiki/vasovagal_response your daughter's reaction was milder than described there and, in fact, vagal reactions do occur in all degrees of severity.
