Numbness in the hands the day after drinking requires vigilance for the occurrence of acute cerebrovascular disease. If the degree is mild, there is no obvious limb weakness, and only shows numbness in the hand, it is more likely to be a small focal hemorrhage or small luminal infarction, and the patient is advised to visit the neurology department to improve the head CT or head MRI examination to help clarify the diagnosis. Alcohol consumption can cause dramatic fluctuations in the patient’s blood pressure, blood sugar and other indicators, especially on blood pressure. If the patient has hypertension or is an elderly patient with underlying diseases such as atherosclerosis, the blood pressure will easily induce vasospasm when it rises after drinking alcohol, and it may also lead to the detachment of existing atherosclerotic plaques, causing cerebral infarction or the rupture of existing tiny aneurysms under the impact of blood flow, causing cerebral hemorrhage.
