one should have an indication of infection by the color of the mucus i. e. clear/white to yellow to green. green being a sign of probable sinus/bronchial infection.
how can i know if my cold/flu has become bacterial? so i can take a ampicillin? . i am aware that ampicillin does nothing if my cold/flu is a virus but i have been sick for a week now and although my body isn't sore/weak anymore i still cough up alot of mucus and coughing hurts my chest a bit and i have a sore throat also runny nose with alot of mucus as well.
