It is not particularly common for beer drinking to cause calf muscle soreness in clinical practice. The possible cause is that alcohol causes vasodilation, and the formation of some unfinished ethanol metabolites causes local soreness after stimulating the muscles. When such symptoms occur, the patient should rest as much as possible, and most of the symptoms can be relieved after 2-3 days as the ethanol in the body is metabolized clean. If the soreness persists and cannot be recovered, appropriate local massage, microwave, baking lamp, and hot compress can be given, and most of the sore muscles can be recovered in a short time. If the symptoms are more obvious, you can try to take some oral non-steroidal anti-inflammatory drugs. If muscle soreness still occurs after drinking alcohol again, it is necessary to consider whether there is a possibility of complications such as rhabdomyolysis caused by excessive alcohol consumption, and patients are advised to stop drinking alcohol if such conditions arise.
