 [ Symptoms ] my heart races for no reason & it scares me to death what do i do when this happens  a heart doc said to walk it off but this sure does not seem reasonable please advise asap [ Disease ] 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
