My ankle was broken a few years ago, now why does it swells evertime i drink alcohol after a few years of recovery?

Comorbidities: How much alcohol are we talking about? One liter of bourbon is much different than a glass of wine. There may have been some other problem in your body incurred when you broke your ankle. Perhaps something along the lines of a disruption of circulation. The alcohol may be disrupting your body's ability control fluids and via gravity the fluids are accumulating in this ankle.
