I was abused throughout my chilldhood and remember being hit in the back of my neck with a baton. I was also snuck up on regularly and hit in the head. My neck now cracks often when i turn my head. The doctors office found no cartilage between c5, 6 & c7. I faintd a week ago and had intense head aches & major spins fo a week. Could synivial fluid be going into my sinuses which are horizontal?
