upper abdomen tender for a couple days after drinking

whenever i drink enough to get drunk (one or two drinks is fine) the morning after my entire abdomen hurts when i touch it. even walking up and down stairs is enough to make it hurt. i’m 20 years old and was a heavier drinker on the weekends for my first two years of college, until this problem started happening. it only lasts for a couple days after drinking and then i feel fine. tried a couple ask doctor forums but i was ignored. ik i should talk to a doctor but do u guys think it’s liver damage or what?
