Dr of Osteopathy Robert Boyd /The Bowling Ball syndrome
When we consider how the spinal structure is fit together almost like a simple but intricate puzzle w the head ballanced on top. How our spine has tendons and muscle intricatly interlacing each of the vertabra, thus interweaving a sophisticated seris of connections, enabling wide ranging smooth movement. We start to get the idea of how one contracted muscle, refusing to relax and thus not in snyc, can cause the breakdown of perfect alignment, which starts a compounding affect, resulting in a miriad of problems in the designed need of function, along the whole spinal line, with the weighted skull resting on top. And the skull connection is integral to the jaws position.(and when we also consider all the nerve pathways that are involved in this arrangement, we can certainly start to understand how this area of our body and its being in right alignment or not, can have great affect on every body system)
Knowing that the problem can be mechanical is one way of dealing w it. Also knowing that we affect our muscular system, and thus the hundreds of tendon connected movments in that spinal orientation, w many of our emotional states, actions and reactions, is another aspect to keep in mind.
Many therapies have been developed and most all can help, some are quick, some are more involved,evan downright exotic as in the inflation of the balloon inserted into the nose tecnique, but as u have experienced, many are temporary, especially if they dont incorporate some aspect of correcting the origin of the circumstance which precipitated the imballance.
Not the easiest, cause it takes our dedication, not the quickest, cause it involves our working on the deeper levels of our living experience, but certainly the most available and the least expensive, is a solo practice of stretching and relaxing, hatha/assanas (yoga).
Not the practices that are designed to raise energy, nor the kind that are meant to achieve some particular position.
As few as 20 min a day can, after a number of months of dedicated regimin, teach us how to relax while existing in tenseness and to experience how that tightness dissapates.
Slowly but deeply we learn to allow our spinal sturcture to adjust itself (our forcing can injure and can evan cause more subtle tension, which is why the advise of a solo practice and strictly having simple relaxation as the goal). Certain tensions, certain imballances (like TMJ), can be aligned out of our system, and no longer manifest or no longer last when they do, because we have learned to relax and allow the natural self aligning of our spine and thus body structure.( not to mention the maturity that can be accessed from the emotional difficulties that are subtley overcome because we have maintained the practice wout egoic interplay and we have done the work ourselves.
