I need help i have a cough im coughing up green mucus ?

Green mucus: If you have had a head cold a week or so ago and are now coughing up significant amounts of discolored sputum, a bacterial bronchial infection is likely and a course of an appropriate antibiotic would be advisable. Contact your physician for instructions.In the meantime drink adequate fluids and take an expectorant cough syrup to continue to raise secretions.
