The pain in the back of the head after drinking may be caused by vasoconstriction, vasodilatation and vasoregulatory disorders.
1. Vasoconstriction: alcohol contains tyramine, which causes the sympathetic nerves in the body to secrete norepinephrine, and norepinephrine will make the blood vessels constricted, leading to changes in blood pressure, making the blood pressure rise, which will lead to the symptoms of pain in the back of the head after drinking alcohol.
2. Vasodilatation: If you drink too much alcohol, it is easy to produce lactic acid or prostaglandins and other vasodilatation substances in the body, so that there is vasodilatation, and vasodilatation is more likely to occur after the symptoms of headache.
3. Vascular regulation disorder: If long-term drinking or smoking, it is easy to lead to atherosclerosis of the head, making the blood supply worse, so it is easier to lead to vascular regulation disorder after drinking, and the symptoms of pain in the back of the head after drinking.
It is recommended to go to the hospital for a relevant examination to clarify the diagnosis, and follow the doctor’s instructions to adopt the appropriate solution. You should try to drink less or no alcohol in order to avoid affecting your health.
