Hi Lisa:
I wish I had a concrete answer for you. About 5 months ago, I was experiencing something similar. Throughout that ordeal, I investigated this phenomenon, and also came up with Globus Hystericus. I did mention it to my ENT and he seemed to want nothing to do with treating it, because from what I read, there are underlying Anxiety issues involved. He mentioned seeing a psychiatrist or a neurologist.
At the time of my experience, I was also taking lorazepam. Only after taking it for about 4 months did I come to believe the lorazepam was creating more of an anxiety response in me, so I stopped taking it and most of my anxiety and that feeling in my throat subsided.
I still am experiencing some levels of anxiety, and the nerves in my throat often react to that and seem agitated. So, I don't know if anxiety is an issue for you, but it might be worth investigating. The more upset you become about this feeling in your throat, the worse it might be getting. The more you focus on it, the more you will notice the feelings. I will soon be seeing a neurologist, just to rule out any medical issues with the nerves, because my whole nervous system seems a bit messed up. But you might do the same, and also consider seeing some type of therapist. I have put that off for some time ... but I think there are some issues I need to effectively deal with in order to reduce my levels of anxiety.
I hope and pray you find the answers you need. God Bless!
