Hello doctor, My husband (age 34) ate outside food on Monday. On that day Night he had diarrhea, vomiting along with fever.  Went doctor next day morning (Tuesday) and they told  he had severe food poisoning.He vomits whatever he had even water and passed loose stools more than 10 times. Taking saline injection twice a day and  below attached tablets. Today he vomits 2 times and passed motion 4 times. But still he had fever  temp is 101. Does food poisoning causes fever?  When will fever subside?
