Cervical spondylosis can lead to fainting. A herniated cervical disc and hyperplasia of the hook vertebral joint can compress the vertebral artery, causing spasm and stenosis of the vertebral artery and insufficient blood flow in the vertebral artery, resulting in inadequate blood supply to the brain. If spasm and stenosis occur in one vertebral artery, fainting will not normally occur. If spasm and stenosis of the left vertebral artery occurs, when the neck is rotated to the right, the right vertebral artery is compressed, resulting in insufficient blood supply to both vertebral arteries, the patient will suddenly faint, and the patient will be fully conscious after falling and can stand up by himself. If both vertebral arteries are spastic and narrowed, fainting can occur when the patient rotates the neck to either side. Treatment includes cervical traction, 1-2 times a day for 30 minutes each time, cervical muscle massage and massage to exercise the strength and intensity of the cervical muscles and restore the physiological curvature of the cervical spine. If conservative treatment is ineffective, surgery is required to remove the intervertebral disc and release the compression of the vertebral artery.
