Hemophilia is a rare disorder in which your blood doesn't clot normally because it lacks sufficient blood-clotting proteins (clotting factors). People with hemophilia may bleed for a longer time after an injury than one would if blood clotted normally. Bleeding that occurs in deep muscle can cause your limbs to swell.
