Hi I am 26 yrs old and one strange thing happened to me which never happened before. When I got really angry, my breathing for fast.. I felt my hands and legs getting numb. I cud feel the blood running through my hands.. and feet for some time . After which I sat down for a while and my fingers were I felt becoming similar to paralytic .. I cud not open my thumb outwards and other fingers unable to close them in a fist... afterwards when I closed my both hands fingers into a fist.. my thumb was shivering and later the hand.. even my jaw as if feeling really cold.. and after a few hours still my fingers are shivering .. I mean when I hold for a while they start shivering but nor much.. also.. I had only some tea and biscuits for breakfast.. after dat I will have same for snacks in the evening.. can u tell me what cud b the reason?
