Dear JMom, I specially logged in again just now in order to write to you (I haven't been logged in for quite a few months). I read your post and I understand your worry. My very best friend who is my age (I am 75 now) broke her neck about 12 years ago. It was because of whiplash in a car accident. She was operated on, and her head was in a sort of cage for quite a few weeks, but today she is fine. I think moving her head to one side is slightly limited, but other than that she is fine. And that was in her 60s. So since your son is a young man I presume his chances of recovery are higher, and I just wanted you to know that it IS possible to recover from a broken neck, and I hope the doctors where he is being treated will be able to do for him what was done for my friend.
Please let us know how things progress. I pray that he will recover.
Love, Esther
