Anyways, a few months ago I went to crack my neck to the left side, my palm under my chin and my other hand supporting the back of my head, I turned to the left, and cracked it, and immediately felt a SHARP shooting pain go down the left side
of my neck
towards the back of the neck
into my upper left shoulder
blade area. It almost made me cry out and I was afraid to move my neck back to normal position. But it passed quickly. It has happened a few other times since then, not constantly.
