When arm pain occurs the day after drinking alcohol, it is mainly due to the large amount of acid produced by drinking alcohol that cannot be excreted and accumulates in the muscles. By drinking a lot of water, milk and tea, you can promote acid excretion and relieve the symptoms. It takes about 1-2 days for arm pain to be fully relieved clinically, depending on each person’s physique. If combined with proper exercise and a reasonable diet, including drinking more mung bean porridge, mung bean water, etc., it also helps the excretion of acid in the body and helps to relieve alcohol. When you encounter arm pain and acidosis, you can also correct it through massage and hot compresses.
