M43.4: Other recurrent atlantoaxial subluxation

The first two cervical vertebrae are located immediately beneath the head. There is a joint between these two vertebrae. It enables you to move your head to the left and right. In your case this joint is too loose. As a result the two vertebrae may be moving too much relative to one another.

You may therefore have pain in your neck, for example, particularly when you turn your head. You may also feel dizzy. You can also get sensory disorders in your hands and feet.
