question: i had a scary incident last night. hot/cold with extreme sweats. heart palpitations. very fast pulse. labored, shallow breathing. fainted. could understand what my husband was saying but unable to respond. thought a warm bath would help but water felt both scalding and freezing at same time. kept collapsing. finally got into bed and soaked clothing 4 times during night. this has happened to me several times before and i have been to the er. each time the doctors said they didn t know what it was and sent me home. i really felt as if i were dying. my husband was sure i stopped breathing at one point.
