Welcome! I’m do glad you posted, @Eaglelady.
There is an active discussion going on about Hyoid Bone Syndrome which has crunching w/ swallowing as one of it’s main symptoms. Depending on where on your neck & how your neck trauma occurred, it could be ES causing the problem, but your hyoid bone might also be contributing. Did the radiologist mention anything about your hyoid bone in the report when you were diagnosed w/ ES?
Here’s a link to a current thread about Hyoid Bone Syndrome. If you search 1speechpick’s posts you can find more information about it.
