The left side of my neck is so stiff and I feel as if I hear a clicking sound when I move my neck
. Two nights in a row I awoke from a dead sleep
with a jump, like a tremor and then of course could not fall back asleep.
I had a MRI of the brain and a C-spine October 2006 and it was unremarkable. Also, this May 2007 I had a CT scan of the brain and again they found nothing. Are these enough tests to rule out a brain tumor?
