Your symptoms sound awfully similar to mine, and I've been to 2 ENTs, had a CT scan and went through a cancer center's ENT surgeon, all who found nothing.
Have you ever looked into LPR, or silent reflux? This is what one ENT told me this might be. Also, the neck pain might be from you poking at your lymph nodes all day, which is what I was doing....
That being said, like you I am still not satisfied with my diagnosis, so I will keep pursuing this until the symptoms disappear or I get an answer I am satisfied with...
Also, this might have something to do with allergies, as they can do weird things to your throat.
I agree with Cheryl, go to a cancer center just to be on the safe side...
