So I've had the stomach flu since Sunday night & its now Thursday morning. I'm starting to get really freaked out that its lasting this long. My symptoms are the usual symptoms, diarrhea, headache, a fever, chills, etc.. I haven't thrown up at all this whole time thankfully. And I thought I was getting better because all the symptoms have went away, except I'm still getting diarrhea. Its just once a day, its not chronic like im running to the bathroom.
