My husband, unknown to me, has had diarrhea on and off for the last 10 days. when he finally told me on Monday, Then I noticed that he was going at least every couple of hours, at least three times at night. He still had some appetite. I started him on gatorade yesterday0we were away from home. Today ont he way home, he started having a headache, had some body aches too, yesteray as well. Now he has a fever 202, and has chills on and off all day. We do have an appointment at the gastro md tomorrow, I have given him some advil during the day., I just gave him two Tylenol. Am I doing the right thing with the gatorade? Tried a little rice and chicken but started going to the bathroom again.
