In sympathetic nerve chain syndrome, the skin may show irritating symptoms, such as increased sweating and hyperreflexia. Sympathetic chain syndrome is a clinical syndrome with multiple causes leading to a long-term recessive existence. When the ganglion damage is severe and the compensatory ability is weakened, typical symptoms appear, which are often delayed in diagnosis and treatment. The clinical manifestations vary depending on the damaged sympathetic ganglia, but all have common clinical symptoms. Such as pain, sensory disorders, vascular dysfunction and so on.
