no the color of mucous does not automatically assume that something is viral bacterial or allergic. it is just a clue. in most cases green mucous is more likely to indicate stagnation (especially if the green is primarily in the mornings). just a like a pond that turns green when water is not flowing in and out the mucous can be green when you are chronically congested. you will need to be medically evaluated in order to determine if the green really has a bacterial association or is just plain 'ol stagnation.
is allergy drainage ever green or does that only indicate a viral or bacterial infection. i have started having drainage from my nose and it has some green color mixed with clear. i am fully aware that a green color doesnt mean a bacterial infection and it may be viral but what i want to know is can it just be allergies and not a virus
