My wife awoke with very bad sweats all over, diahrea, very cold and clammy skin, threw up a little. She started shaking and did not know I was there for only a moment. She is refusing to go to Emergency. After 30 minutes, the sweats got better, but very cold skin and clammy. Do you think it could be the flu? Im not sure what to look for this year. I was also concerned about a stroke, but no pain or drooping of anything at this time.
