As summer passes and the weather turns cool, many patients with cervical spondylosis suffer from the same old problems again, neck and shoulder pain, numbness in the fingers, dizziness and headache, and in severe cases, numbness and weakness in the limbs, unstable walking, urinary and faecal dysfunction and even paralysis, which have a serious impact on the work and life of patients. So what is cervical spondylosis? To be precise, it is a clinical syndrome that produces a series of symptoms due to degenerative degeneration of the cervical disc, cervical disc herniation, cervical spine osteophytes and ligament thickening, which stimulate or compress the cervical spinal cord, nerves and blood vessels. According to the characteristics of symptoms, cervical spondylosis can be divided into the following types: cervical, nerve root, spinal cord, vertebral artery, sympathetic and mixed types. The occurrence of cervical spondylosis is related to cervical spine degeneration, poor posture and long-term strain. Lower temperatures often induce an increase in cervical spondylosis. This is because cold stimulation causes spasm of the muscles and fascia, and the spasm leads to an increase in metabolites while being very detrimental to the removal of metabolites, which creates pain. Pain in turn can stimulate the production of further spasms. The spasm and pain form a vicious circle, resulting in a worsening of symptoms. Therefore, it is very important to pay attention to the warmth of the cervical spine for those who are not so good. Many friends have noticed that when the neck and shoulder back pain, a dash of hot water can significantly relieve the pain, the reason is here. Of course, if the symptoms are more severe, with severe pain, numbness in the arms, weakness in the limbs and unsteadiness in walking, it is still necessary to go to the hospital as early as possible. Receive professional and standardized treatment as early as possible.
