I ve been having mild flu-like symptoms for the past couple weeks, including nausea , dizziness , fatigue, confusion, muscle pain, and intermittent fevers (without the other symptoms that usually accompany my flues and colds) and was wondering if this could be related to a trip I took six months ago to the tropics and/or if these could be malaria symptoms . Also, to avoid the hassle: no, I m not pregnant.
