I understand what you are going through. 2 months ago, I started having the symptoms of lump in throat when I swallowed, hoarseness , voice starts to strain when I talk for a while etc. Went to my doctor who couldn't see anything but sent me to an ENT who did the same scope of my upper esophagus, throat, nasal etc and told me that it was irritiation from reflux, put me on a PPI and told me it should help and then sent me for a barium swallow.
It's been 2 weeks now and I still don't notice much of a change in my throat symptoms, so I'm not worried that they won't improve at all.
I have a followup appointment with my ENT once the intial 6 weeks of the PPI are done.
