Thank for asking to HCM
I really appreciate your concern the given history is suggestive of intestinal infection, if I would be your doctor then I would advise you, not to worry about this most of the diarrhea
are self limiting, only hydration is matter, for the vomiting
you can try "Tab Domepridone 30 mg twice in day" if condition does not improved then Tab Metronidazole
400 mg twice a day for five days can be tried , take care and have nice day.
