The numbness of the face the day after drinking alcohol may be caused by long-term alcohol consumption that damages neuronal cell membranes and causes peripheral neuropathy. Since alcohol is a pro-neural substance, it can cause inflammatory changes and degeneration of nerve cells, and in serious cases, it can lead to irreversible damage, so you should quit drinking in time, and you can also consider taking oral nerve-nourishing drugs such as methylcobalamin, vitamin B1, rat nerve growth factor, coenzyme q10 and so on. In addition, if there is violent vomiting after drinking alcohol, resulting in a large loss of digestive juices, there may be hypokalemia, which can also cause symptoms of facial and limb numbness, which can be clarified by ion analysis, and the symptoms can be quickly relieved by intravenous potassium chloride supplementation.
