Depends: Swelling naturally occurs with legs down and engorgement of the veins can look purple. Elevate your legs and see if the color changes. If so, it's associated with venous reflux. If the foot remains swollen, this may be an emergency that the circulation is compromised where a clot or an infection could be present. If in doubt, have it checked out. A podiatry consult would be good.
