Hi! I Am Wondering What Might Be Causing A Recent

Hi! I am wondering what might be causing a recent problem in my throat. I have sudden fits of gagging I can sense ahead of the "attack" because my eyes will water and I instantly loose my voice or it will go very hoarse. My neck is always sore. It also feels like there is something stuck in my throat however I've had a scope done by an ease nose and throat dr to my larynx and nothing was found. Symptoms have not gotten any better and this has gone on for about four months. Any ideas?? Thank you!
