I've had a cold for about 5 days with as cough & mucus. In the morning the mucus is dark green & the cough is NT getting any better. Should I go in?

I've had a cold for about 5 days with as cough & mucus. In the morning the mucus is dark green & the cough is NT getting any better. Should I go in?

Cough + cold symptom: It would be difficult to determine what is causing this without being seen. Green mucus can occur in the morning naturally as a cold is resolving and does not necessarily mean there is an infection. If you have a fever or the symptoms last longer then 10 days then you should see your doctor. You can try saline nasal spray and Mucinex (guaifenesin) to loosen the secretions if there is no fever. ...Read more

Productive cough: The purpose of a cough is to clear unwanted material from your respiratory tract. The material you are taking is a substance designed to liquify the mucous and aid in the clearing of secretions but will not stop you from coughing. If it is keeping you awake you might try something with dextromethorphan in it. Check with your friendly pharmacist. They will have suggestions. ...Read more
