It is generally not recommended to use a round pillow continuously, especially with a round pillow pillow overnight. Because at this time may cause excessive compression of the cervical spine, resulting in compression and irritation of the blood vessels and nerves on the posterior side of the cervical spine, which then causes complications. If the patient wants to use a round pillow for continuous correction and relaxation, you can take the following approach: 1. Pick a relatively thin, short round pillow that can only do the job of supporting the cervical spine; 2. You can put it under the cervical spine and pad a pillow of similar height in the pillow. And the pillow can not be too hard, for example, you can use materials such as buckwheat bark as filling, so that patients can use round pillows with confidence. Some patients are not suitable for treatment using round pillows, often common in spinal cervical spondylosis, once the doctor informs the patient currently has this disease, it is recommended to listen to the doctor’s advice, do not use a round pillow.
