Re: how to treat thick phlegm in the throat
One possibility is allergies. If the phlegm is clear, white or pale yellow, this may be what's causing it. I am dealing with the same thing right now. It came on all of a sudden last year (I'm 38), and I have it almost daily. I went to an allergist and had testing done. I've been on allergy shots for about 6 months and have seen slow improvement.
