I cannot clear my throat; feels like mucus is there. Suggestions?

This is @juleszs--- I have a condition that has lasted about 1 and 1/2 years. I feel like I have phlegm in my throat but I can not bring it up. I have been scoped 4 times by an ENT doctor I have tried GERD meds. I have been to an allergy doctor. He tried asthma meds. Nothing helps.
This condition goes away when I sleep. As soon as I move around in the morning the congestion returns and stays with me all day---it feels like there is a lump in my throat.
Background ------ In January, 2020 I had neck surgery----- C 4/5. Maybe the breathing tube nicked my throat. This condition started just after the surgery. However-- I have had this condition twice before in the 27 years that I have lived in Florida. But it has gone away in due time. Now it is here to stay.
Please comment!

Hi!
That is too bad about your throat problem! It must be terrible! I have a very sensitive throat and for years I was susceptible to sore throats constantly. However after I started using original Listerine after every meal, I have had no sore throats at all. It's very good about getting mucus out and getting the soreness to go away after only a few uses. Don't use the flavored Listerines. They don't work at all. Another thing I used before I found Listerine was to gargle with hot salt water. That worked pretty well but the Listerine was much better. I hope this helps.

Update from JULES,
I have had my throat condition for over 3 years. ENTs can not find any help for me. I live with the discomfort.
Menthol cough drops helps for a short while.

Any new magic?

@juleszs -- Sorry to hear the doctors have not been able to figure out what is causing your symptoms. Here's some information that sounds a lot like what you are describing.

What is globus pharyngeus?: https://www.medicalnewstoday.com/articles/318633

Have you thought about seeking help at a teaching hospital or major health facility like Mayo Clinic? f you would like to seek help from Mayo Clinic, contact one of the appointment offices. The contact information for Minnesota, Arizona and Florida can be found here http://mayocl.in/1mtmR63.

I must comment about your suggestion to contact Mayo Clinic. I tried to make an appointment with Mayo Clinic in Phoenix for my throat clearing and got turned down. I don't know why and it makes me suspicious about them. So, I am not at all impressed with the Mayo Clinic!
