Being a Bellevue chiropractor, and after seeing thousands of patients over the years, I have begun to see certain patterns in certain groups of patients. For instance, woman who wear high heels for many years have a VERY high likely hood they will have low back pain. Another one is people who have computer jobs all have very similar neck and back problems, and their necks all have a certain look to them. This has become so common in the city that I practice, Bellevue WA, because of the many computer jobs, that I have coined the term "Bellevue Neck".
So why do these people with computer jobs all have similar looking necks? Sitting at a computer causes the head and neck to tip forward, and then jut forward. If you keep the head and neck in this posture for long enough it will get stuck there. This is a bad thing.
In neurology we call this process plasticity. Think of your spine like a piece of plastic, bend it too far and it will get stuck there. On the positive side of things, you can also bend things back to their normal position with the right treatments.
I have coined the term "Bellevue Neck" for those with straight necks or a loss of neck curve. A lost curve in the neck can cause headaches, neck pain, middle back pain, and even low back pain if it is a bad enough case.
I work with patients on a daily basis who's neck pain, mid back pain, headaches, tmj, and so on, are due to their "Bellevue Neck". The key is to reverse the damages done and then prevent them from happening again. Chiropractic care is the best suited form of treatment for cases of Bellevue neck, and specific exercises are important to keep your spine in place.
