4. Tenderness of the Skin
When a blood clot has formed in the leg it may result in a feeling of tenderness in the skin at the site of the clot. While the clot itself is not at the surface of the skin and is actually in a deep vein, this feeling may still occur. There will usually be no signs of disturbance on the outer surface of the skin itself. However, sometimes the veins at the site of the clot may start to appear more visible if the blood clot has become quite big after being left untreated for too long.
This feeling can actually occur in the other leg which is not affected by a clot due to the fact that you start to put more weight on your healthier leg in a subconscious effort to alleviate the pressure. In this case, the healthier leg will often experience strains in the muscles and joints from the added pressure which can cause similar symptoms to what is experienced in the leg affected by the clot.
