Hi i'm 26 years old, 5'9, and 128 lbs. I suspect I had food poisoning, my symptoms started at 6 am on sunday (diarrhea, vomiting, abdominal cramping, nausea). It is now tuesday, vomiting and diarrhea have subsided but I still feel sick to my stomach and now I feel extremely bloated, having sharp lower abdominal pain, and my lower back hurts, what should I do?
