The old feeling of something moving inside the back may be caused by vegetative nerve disorder, or it may be caused by cervical spondylosis. 1. Plant nerve disorder: Plant nerve disorder belongs to functional diseases, most patients are due to long-term late night, anxiety, black and white reversal and so on. The disorder of plant nerves can also affect many systems of the whole body, causing imbalance of the regulation of sympathetic and parasympathetic nerves of the body, leading to the occurrence of wandering pain and wandering sensory abnormalities throughout the body. 2. Cervical spondylosis: Cervical spondylosis can lead to dehydration of cervical intervertebral discs and displacement of cervical intervertebral discs. The displacement of cervical intervertebral discs may cause compression of the posterior and lateral nerve tissues, resulting in sensory and motor abnormalities below the plane of nerve compression. The symptom of feeling something moving in the back also needs to be considered as a cold stimulus, mental factors, etc., and needs to be combined with the characteristics of the medical history and the relevant examination results to make an accurate judgment, and it is recommended to clarify the cause of the disease under the guidance of a doctor.
