Dh has been throwing up for 4 days now. Started feeling unwell on Thursday. Was sick Friday, Saturday and Sunday whenever he ate or drank. Felt better today and managed to keep water and hot drinks down so he had some light lunch and immediately threw it up. I wouldn't expect a bug to go on this long. Whenever I've had them they are utterly grim for a day or two but then they stop as soon as they started. This feels really prolonged and other than the sickness and weakness from not eating properly he feels ok.
Any suggestions? He is reluctant to see a doctor because he thinks it'll just be fobbed off as a bug.
