Vertigo is a condition whereby you loss your balance and your sense of orientation in space. It is triggered by a movement of the position of the head and is often accompanied by dizziness, headache, nausea or neck pain. Movements may involve sudden head motion, tilting of the head or even rolling over in bed. It can be made worse through a lack of sleep, changes in barometric pressure or by mental stress.
Chiropractic research has found that many types of vertigo (such as Benign Positional Vertigo) are caused by neck problems.
The two vertebrae located directly under the head are the C1 (known as Atlas) and the C2 (known as the Axis). They are chiefly responsible for the rotation and flexibility of the head and neck. As such, they are extremely vulnerable to injury and upper cervical trauma.
Patients may be able to point to a specific moment of trauma such as a car accident which resulted in the vertigo problem but it may be many months after the particular event before symptoms occur. Because there are so many nerves which transmit through the upper cervical spine to and from the brain, any displacement of the vertebrae (even slightly) may result in vertigo. Symptoms will generally persist until the neck injury is addressed by the chiropractor.
Chiropractic care involves adjustments to the spine, especially to C1 and C2, to realign the displaced vertebrae. These will generally reduce or eliminate the vertigo completely.
