My husband has had bad diarrhea and vomiting for going on 4 days and now for the past 2 he had noticed blood in his bowel movements could this be just a hemroid or something more seriouse?
He needs to go to the ER for rehydration, and to find out what is going on. Never assume anything when blood is seen in the stool, it needs to be checked out. Your husband has to be dehydrated because there's no way to keep him hydrated when he's going from both ends. Dehydration is serious and can be fatal.
