Why do my feet swell when I travel to Mexico?
Why do my feet swell when I travel to Mexico? Mild swelling of feet and hands may occur when first exposed to hot weather. This effect is more common in females. Swelling occurs when the blood supply to the skin increases which also radiates heat; fluid moves out of the blood vessels and into the tissues causing swelling.
How long should swollen feet last after flying?
If your feet and ankles swell during a flight but the swelling subsides shortly afterward, it's not a serious concern. But if the swelling continues for hours after the flight and if the leg is red or warm to the touch or you have symptoms in only one leg, you need to seek medical care.
