Cervical spine misalignments do not usually heal themselves easily. The plane of each small cervical joint has a certain angle, and there are joint capsules outside the joints, which are protected by very dense muscles and ligaments. The cervical spine misalignment is not easy to correct by itself, which can lead to the gradual aggravation of cervical spondylosis, and fewer patients are self-healed. Cervical spondylosis is best treated by a specialist, and some patients can heal themselves by hanging upside down, using gravity to gradually pull and adjust the muscle system of the neck, which can lead to the misaligned cervical vertebrae, especially the small joints at the back, to reset themselves.
