2 years ago I had a c-5 c-6 discectomy in which they used a cadaver disc and hardware. aside from a small amount of pain every once and awhile i have had no problems. 4 days ago i was in a car accident in which we were rear ended and my neck snapped forward and back. within a few minutes i suddenly felt like something was stuck in my throat every time i swallowed. i went to the er and they gave me nsaids and muscle relaxers but over the past 4 days it has only gotten worse, and now its not only when i swallow, it is constant. is this something to do with my surgery or am i worrying over nothing?? someone please help because it is making me go crazy! thanks in advance!
