Headache caused by hangover can be completely relieved in about 1-2 days. Headache caused by hangover is mainly a manifestation of alcoholism. After drinking alcohol, some components of alcohol will have a stimulating effect on the central nervous system of the brain, causing cardiovascular and cerebral vascular contraction and diastolic dysfunction, causing patients to have headache symptoms. In this case, the patient should be given symptomatic pain medication to relieve the pain, such as oral Danjin headache capsule, Aminophentoin tablets, pain relief tablets, indomethacin and other drugs. The whole body muscles can also have a certain effect on the headache.
