Daytime work at night hand numbness and swelling pain is mainly caused by overstrain resulting in local muscle blood circulation disorders, cervical spondylosis, cerebrovascular disease and so on. 1. Excessive strain: excessive strain and stress during the daytime work leads to local muscle tension and spasm, and cause blood circulation disorders, at night due to the vagus nerve excitation, concentration and thus the morning hand numbness and swelling pain performance. 2. Cervical spondylosis: due to overwork during the day, resulting in cervical spine force, stimulation of the surrounding blood vessels and nerves, resulting in nerve compression symptoms worsening, resulting in numbness and swelling in the evening performance. 3. Cerebrovascular disease: such as cerebral infarction or cerebral hemorrhage, causing numbness and swelling pain in the right hand, through CT or MRI examination. The hand numbness and swelling pain at night can be relieved after resting during the daytime, and is not accompanied by other special discomfort symptoms, only need to pay attention to rest. Excessive physical stimulation of peripheral nerves leads to edema, resulting in symptoms in the corresponding innervated area of the nerve. For example, irritation of the median nerve at the wrist results in numbness of the skin of the radial half of the palm of the hand and the three and a half fingers on the radial side of the hand. The diagnosis can be confirmed by electromyography. It is recommended to go to the corresponding specialized outpatient clinic in the hospital to complete the examination and make a clear diagnosis before treatment.
