There are physiological and pathological cervical bulge, physiological does not need to be corrected, pathological cervical curvature changes in the correction of cervical traction, surgical treatment and so on. Under normal circumstances, the cervical spine has a forward physiological bulge, which is a normal phenomenon with a cushioning effect and does not require correction. If the cervical spine has a physiological curvature change, and the cervical spine straightens or even bulges backward, intervention is required. Cervical traction can be used to relieve neck muscle spasm, which is beneficial to the recovery of cervical curvature, and can also be combined with neck muscle exercise and acupuncture to enhance the efficacy of treatment. If conservative treatment is not effective and the change in cervical curvature leads to nerve compression, surgical treatment is needed to release the nerve compression. After the examination found that the cervical curvature changes, it is recommended to consult a doctor in time, under the guidance of the doctor.
