A blood clot is a gel-like, semisolid clump of blood. When it forms in a vein deep inside the body, it is called deep vein thrombosis. This is a life-threatening condition that usually affects an individual’s thighs and lower legs but can also form in other body parts. Detecting the problem early is crucial to prevent serious complications. So, here are the common early warning signs of deep vein thrombosis that should not be ignored.

1. Swelling

Swelling in one of the limbs is a very common early warning symptom of deep vein thrombosis. Typically, the swelling occurs in either of the legs. However, in some cases, the arms are affected first. The swelling occurs because the body’s blood circulation is poor, preventing enough oxygen from reaching critical organs. If an individual notices unexplained swelling in any of their limbs, it might be because of blood clots in their veins, and they must get it checked immediately.

2. Pain

Pain is another common early warning symptom of deep vein thrombosis. Pain due to a blood clot in the vein is usually felt in only one leg and often starts in the calf. The pain is generally mild. However, the area may become sore, tender to touch, or achy. It tends to worsen when an individual walks or stands continuously for long, and resting may not provide any relief.

3. Muscles cramps

People with deep vein thrombosis may experience muscle cramps in their legs, especially at night. These cramps start in either calf, causing a lot of pain. Such a condition is called a charley horse. However, there is a difference. Pain caused by charley horse typically subsides in a couple of minutes. However, a deep vein thrombosis blood clot can trigger a calf cramp that is intense and is unlikely to get better. Even stretching, massaging, or walking does not provide relief.

4. Skin discoloration

If a blood clot occurs in a vein deep inside the body, the color of the skin surface may change. This happens because there is no blood flow in the affected area. People with deep vein thrombosis commonly notice that a portion of their skin turns red, and they experience pain and swelling in that portion. The skin may also turn bluish and dark, and this color may remain until it’s treated.

5. Warm skin

People with deep vein thrombosis experience skin warmth due to abnormal blood circulation. Since the blood cannot flow properly through the affected area, the blood fills more of the outer veins, causing warmth. An individual with this symptom will distinctly feel the warmth as it is only limited to a particular spot and relatively warmer than the surrounding skin.
