Does anyone know whats the difference of a fever or flu. I'm so sick right now and just dont know whats the best thing to take care of myself. I went to see a doctor already and she said to take pills for the body aches and that was it. One minute I feel like I'm normal then the next I'm laying in bed sick like a baby. Sore throat, heavy pounding headache, body aches, hot sweats and cold chills. It is so uncomfortable.
