When the blood flow in your legs becomes constricted due to clotting, the area might become red and irritated. Blood will pool behind the clot, which can cause the smaller blood vessels just under the surface of the skin to burst or swell. The area can become hot to the touch, as well. If you notice an unexpected redness accompanied by pain in one leg it could be a sign that there is a blood clot causing a blockage in a deeper layer of the bloodstream. If ice or elevation do not alleviate the redness, visit a doctor to make sure there are no clots.Next
