Is it same as every morning waking up with mucus in the throat? Kinda thick/hard - sometimes it flings out when I cough it out. Doctors have me had samples tested but there was no infection. So they just write 10 days Allegra (and a month saline water spray 3-4 times a day) and that's it. But it keeps happening. Been happening since last 2 years.

And then almost nothing the whole day except this feeling remains that something's there in the throat but rarely anything comes out - sometimes some semi-mucus (?) (or just spit - white but slightly thicker than spit - comes out)
