Yesterday, I experienced excessive sweating to the point of dripping (I was in an air conditioned hom,e at the time), and then I felt weak followed by numbness across the shoulders and down both arms. After about 3 minutes, this subsided, but then, I had the chills and could not get warm. The chills lasted about an hour. This afternoon, I am experiencing very loose bowels (diarrhea). Am drinking water and drinks with electrolyes. What could this indicate?
