The symptoms of soreness in the right arm after drinking alcohol: 1. It may be due to the increased burden on the liver caused by regular drinking and the weakened ability to detoxify the liver, which causes a large amount of acid in the alcohol to enter the muscles of the right arm and then causes pain. 2. It may also be due to gouty arthritis, which increases the purines in the body after drinking alcohol and then converts into elevated uric acid, which is present in the muscles of the right arm and around the joints for a long time. 3. It is also possible that due to the high alcohol content in the blood, lactic acid will increase with the oxidation process of ethanol, causing pain in the arm. So after drinking alcohol the right arm pain should first quit drinking, and within a short period of time the symptoms are not relieved, you must go to a regular hospital in time for treatment.
