Welcome to just answer
No I do not think that the swallowing problem you have is due to the scar form cervical fusion surgery
Rather I would consider Globus hystericus to be the likely cause of your swallowing difficulties
What is that?
Its a persistent sensation of having a feeling of obstruction in the throat when there is none.
Do you have any more info?
Swallowing can be performed normally, so it is not a true case of dysphagis but it can become quite irritating.
One may also feel mild chest pain or even shortness of breath when swallowing.
So, it's all in my head?
