There are two general causes of hand numbness. One is a head cause, such as having a head occupation, which is a tumor or an infarction or bleeding in the head, which can cause numbness in the hands. The second is cervical spondylosis, which can lead to hand numbness symptoms. If your hands become numb after drinking alcohol, you must pay attention to whether it is the increase of blood pressure caused by drinking alcohol or the occurrence of cerebral infarction or cerebral hemorrhage after drinking alcohol, so if your hands become numb after drinking alcohol, you must go to the hospital for routine CT examination and observation. Because CT cannot be seen in the early stages of infarction, it is important to observe for at least 24-48 hours and then review to confirm whether there is an infarction. If your hands become numb after drinking alcohol, you must stop drinking, go to the hospital for a CT examination in a timely manner, and see a specialist for diagnosis and treatment.
