I Recently Got Back From Vacation In Charleston, SC And

I recently got back from vacation in Charleston, SC and the humidity/heat were high, plus I was eating a good amount of salty, non-healthy foods and drinking alcohol. During the trip, my feet were consistently swollen and would decrease overnight. Now that I'm back home (in NY), I thought the swelling would completely go away but it hasn't and my legs also feel heavy from the knees down. Wondering if I should be worried that this is something more than being bloated?
