Since yesterday I have been having symptoms of flu,body aches, chills dizziness, headaches, lack of energy and nausea. But do not have a cough, sneezing, runny nose, or sore throat. Could this still be the flu or is flu season over. It came on all of a sudden, one minute I was fine then the next I was laid out in the bed. Just doesnt feel like the flu i've had in the past.
