Hi there. Starting on 3AM last Friday, I started having symptoms of what I thought was the flu going around. Diarrhea, vomiting, fever (101.5), muscle aches (mild to severe), sweats and chills, stiffness, weakness, some dizziness, no appetite. I automatically assumed it was the influenza virus but in almost everywhere I read, it says a cough and/or sore throat almost always follow. I've had neither, nor have I had any chest pain.
