I have been in extreme heat and humidity today. Temp around 125°, and very high humidity. Little exposure to sunlight, just heat, for about 9 hrs daily for weeks now. Today I came home, and had been in the air conditioning for a few hours when I suddenly got very cold, to the point of shivering and teeth chatter. Also, developed a fever of 102° I am hot to the touch (my face and body) but freezing cold. What do you think is going on here, Doc? Am I in danger?
