These are just part of the progression. Sometimes, we are doing good so we start to subconsciously increase our movement. I find that I need to be careful to only move in one plane at a time. Up and down or side to side but not both. I also found it helps to learn to look to the side with more shoulder movement. I'd come in from the back yard from looking for dog droppings and feel miserable. When I stopped the neck based head turning and turned with my shoulders, I did much better. It may be that I turned slowed from the shoulders. I also know that I have C-1 and C-2 problems for over 16 years. I can't figure out how that would contribute to the symptoms.
