There is also cervical spondylosis. When the cervical intervertebral disc protrudes and compresses the adjacent cervical nerve roots, there will be symptoms such as finger numbness and abnormal sensation. In this case, you can massage your arms more at night or find a comfortable posture before going to bed. Don't fall asleep, lest you wake up numb.
In addition, we can also choose a pillow with a suitable height, so that our head and neck can rest on the pillow to keep the blood flowing. At ordinary times, we should pay attention to avoid working at the desk for a long time, watching mobile phones and doing cervical spine exercises.
