I vomit and then get watery diarrhea and it s gone in 24 hours. But it comes back regularly. Sometimes within 2 days, sometimes over a week and even a month. An emergency room visit ruled out anything serious . Could I have a parasitic problem or a bacterial infection? I m trying apple cider vinegar, oregano oil tablets, garlic, etc. I am thinking I m going to be ill again in the next 1/2 hour. Help? Ps/I went to a dr a week ago and he blew me off as something not serious,Minot worth worrying about. I m quitting him!
