For me it is extremely important to create structures that keep my life as simple as possible. Step by step, always one by one.
If you are standing right at the very beginning of this disease everything is confusing and it is hard to know where to start.
I think a clear diagnosis should be the first step to take, using:
X ray in flexion, extension and maybe rotational views
or even a combination of two or more.
And if necessary an additional test like neurovegetative diagnostics. Unfortunately, there are no strict guidelines for the diagnosis of ligamentous instability without bony injury which is why they are often missed.
As a little help there are some angles which could be measured, but also in this case the opinions about what a pathological angle is are not entirely clear.
It is often necessary to ask for a second opinion. Four eyes do see more than two.
2. Non invasive treatment options
As soon as it is clear where the cervical spine is damaged the next step would be to find the right physical therapy.
Unfortunately there is no therapy that works for all of us.
My personal rules for therapy can be found here.
3. Surgical treatment
If no non invasive treatment leads to improvement or if symptoms even become worse then the last option is surgery.
Again there are some things to consider before surgery, have a look here.
