Elevate feet see doc: If the unexplained swelling lasts for more than a few days or is worsening it is a good idea to see your primary care doctor or an internist.Swelling of the legs is usually due to fluid retention. Caused by (heart, kidney, liver, high BP salt intake etc) needs to be sorted out by primary care doc/internist. Unilateral (one side) maybe due to a blood clot, muscle or tendon injury or arthritis.
