Numbness may be caused by physiological factors, such as maintaining a posture for a long time, or it may be triggered by cervical spondylosis, cerebral hemorrhage and other pathological factors.
1. Physiological factors: If you keep a posture for a long time, the body is compressed, resulting in poor blood circulation, then numbness may occur, and can usually be relieved after changing the posture and resting properly.
2. Pathologic factors:
(1) Cervical spondylosis: such as cervical disc herniation, it is easy to compress the nerve root, which may cause localized numbness.
(2) Cerebral hemorrhage: due to the rupture of intracranial cerebral blood vessels leading to blood overflow, edema and bruising in the skull, edema and bruising will be compressed to the neural tissues will appear in the limb dysfunction, thus causing numbness in the body.
Numbness can be caused by a variety of reasons, after excluding physiological factors, we should consult the doctor in time, complete the relevant examinations and carry out treatment under the guidance of the doctor.
