If a patient has symptoms of neck discomfort and nausea, it may be caused by several reasons: 1. It may be caused by cervical spondylosis. There are many cervical spine diseases that may cause the above symptoms. For example, during an attack of sympathetic cervical spondylosis, it is possible that sympathetic nerve irritation in front of the cervical spine has led to neck symptoms and the presence of gastrointestinal irritation at the same time. In vertebral artery cervical spondylosis, there is pain in the neck due to compression of the vertebral artery, and there is a lack of blood supply to the brain. This can also produce nausea. In addition, if the patient has some compressive factors in the front of the cervical spine, resulting in the compression of the esophagus, similar symptoms will also occur. 2. It may be caused by the large blood vessel lesions in the neck. For example, a thrombus or a large number of atherosclerotic plaques in the large blood vessels of the neck may cause symptoms in the neck and nausea due to reduced blood flow to the brain. 3, may be caused by lesions in the throat. For example, the presence of inflammation or infection in the throat may also cause the above symptoms.
