Redness
Due to a dense buildup of blood under the skin surface in your leg, there might be visible redness in these areas. In most cases, this is often the first symptoms of the condition when a clot is forming deep in your vein. Over time, the spot might grow in size and spread to a larger area. When you experience some persistent red skin patches in your legs, especially after a surgery or injury, it is advisable to visit your doctor or healthcare provider. This condition won’t go away quickly or even get worse. [2]
