Hi, I ve been having flu like symptoms for a few weeks. I ve been experiencing diarrhea, constipation, pain in my stomach (stomach gurgling), feeling week, no fever using a thermometer although I feel like I have a fever, sweaty, feeling of nausea (like I want to vomit). It s been mostly affecting me on the weekends but goes away during the week. I m not on any diet or taking any meds aside from anti-depressants. I was wondering if it is possible to experience a flu for weeks but have it come and go? Or else could it be something else?
