I have had an upset stomach, diarrhea and nausea for the past 4 days. Every time I eat, I end up running to the bathroom. I haven’t actually thrown up, I’ve only been feeling like I am going to. I’ve tried pepto and it hasn’t been working. WHat could have caused this? what should I do? Im feeling miserable and I feel like I cant eat because all I end up doing after is having to go to the bathroom.
