Hi Boydville,
Qigong is very effective for spine work. Many of the techniques focus energy there, which can't help but produce favorable results, throughout one's system. Just the simple elongating and alignment of the spine, suspending the crownpoint, in a basic qigong posture can have transformative results, just like something as simple as a smile turned inwards. These should be felt very openly, and as a progressive state of relaxation, as opposed to any force.
This post brings another idea to mind. Many people post here, asking if qigong will help this or that specific blockage. One should remember, that qigong is a very effective 'preventative' , lifestyle practice. You are more than your issue or blockage. Look at yourself as a whole, and how a daily practice of qigong address's your whole being. Start addressing your whole being. Your specific blockage will get swept away in this process, as you take care of aspects of self you may or may not even be aware of. Qigong is not just something to be taken out of the medicine cabinet for application to a single blockage that has reared its head in your physical body. It is stellar, as a preventative practice, a life style change... The blockage gets addressed as you shift your lifestyle up to a higher state of being, living healthier, and keeping 'everything' open, and flowing.
love,
