I had those same issues - food getting stuck in throat, choking on water. I also snored when I was sleeping and snorted when I laughed (neither of these things did I ever do prior to my injury ). I did have alot of neck pain and stiffness during that time.

All of these symptoms disappeared a few months ago. I have had a stressful summer with alot of other symptoms worsening - but these particular issues have not come back.

I have been paying close attention to my neck (thank you MarkinIdaho for all of your advice on neck posture!) and I do beleive that all of these issues were related.
