I, too, suffer from those same symptons as most of you have listed:

lump in throat
hoarseness
throat clearing
etc etc
I am on Nexium and Zyrtex as Nasonex for allergies. Symptoms are only in the morning now. But without meds-- they are there all day and really extreme. I have been dealing with this for about 4 years now and every test shows no problem. I was beginning to think this was in my "head" until I read these posts. I just keep taking the meds and hope no long term damage is being done.
