Numbness in the fingers at night may be caused by cerebrovascular disease, cervical spondylosis, peripheral neuropathy, and plant nerve dysfunction, as follows: 1. Cerebrovascular disease: It is the most common cause of numbness in the fingers at night, which is mostly seen in middle-aged and elderly patients, mostly unilateral finger numbness, and patients need to be diagnosed promptly through CT, MRI and other imaging examinations. 2. Cervical spondylosis: It can lead to bilateral finger numbness. 3, peripheral neuropathy: peripheral lesions such as Green-Barre syndrome and peripheral neuritis can also easily lead to bilateral numbness of the fingers. 4, phytodysfunction: some menopausal women also experience numbness of the hands, dizziness, headache and other symptoms due to phytodysfunction. Patients need to go to the neurology department in time to get a clear diagnosis through relevant examinations and then give targeted treatment.
