Discomfort in the cervical spine may cause symptoms of drowsiness, which is due to sympathetic cervical spondylosis, because there are more inflammatory and hyperplastic lesions in the cervical spine area, and in the case of excessive fatigue of the cervical spine after prolonged head-down ambulation, if it is accompanied by cold in the cervical spine, it will easily lead to an increase in local inflammatory metabolites and push accumulation. This will lead to stimulation of the sympathetic nerve chain on both sides of the cervical spine, resulting in sympathetic hyperactivity or inhibition, which may lead to symptoms such as weakness and sweating. After the appearance of weakness, it will easily lead to drowsiness and other related reactions, and some patients may also experience other symptoms such as dizziness, headache, nausea, vomiting, chest tightness, panic attacks, etc. Therefore, after this situation, you can first take a cervical spine area massage, which can effectively relax the muscles and promote the metabolism of inflammation, and can also effectively accelerate blood circulation. In addition, you can use a warm water bag to increase the local blood circulation, can also effectively relieve the symptoms. After drowsiness can not simply be thought of as caused by sympathetic cervical spondylosis, sometimes if there are intracranial abnormalities, such as cerebral ridge blockage, brain atrophy, and other diseases of the brain, there may be drowsiness symptoms. If available, it is best to go to a hospital for relevant medical examination to clarify the condition before treatment.
