Would anyone have any sort of idea as to what this situation would mean:
i had a terrible problem the other night where I had been working out and breathing rather heavily. All of a sudden my entire body froze up. My whole self had that lightheaded feeling where you just feel numb and like you have all sorts of pin sensations throughout your skin. My hands and feet locked up so much that I could not open my hand and move my fingers myself. It was as if my muscles had frozen up in the position they were in and an imaginary person had a grip over my clenched fist. A friend of mine had to try and pry my fingers open to just to get them to open up and move around. Any ideas as to what this would be?
