A blood clot in the leg—medically called Deep Vein Thrombosis (DVT)—can be serious because it may travel to the lungs. Here are 10 warning signs to watch for:
1. Swelling in one leg
Usually affects just one leg (often the calf). The swelling can come on suddenly.
2. Leg pain or tenderness
Often feels like a cramp or soreness, especially in the calf.
3. Warmth in the affected area
The skin over the clot may feel noticeably warmer than the surrounding skin.
4. Red or discolored skin
The leg might look reddish, bluish, or darker than usual.
5. Shiny or tight-looking skin
Swelling can make the skin appear stretched or glossy.
6. Enlarged veins
Surface veins may become more visible or swollen.
7. Pain when walking or standing
Discomfort may worsen when you move or put weight on the leg.
8. Persistent leg fatigue or heaviness
A feeling of fullness or heaviness in the affected leg.
9. Mild fever
Sometimes a low-grade fever accompanies a clot.
10. No obvious injury
Symptoms appear without a clear cause like a pulled muscle or trauma.
⚠️ When to seek urgent care
If you also experience:
- Sudden shortness of breath
- Chest pain
- Rapid heartbeat
- Coughing up blood
This could indicate a Pulmonary Embolism, which is a medical emergency.
If you suspect a clot, it’s important to get medical attention promptly—early treatment can prevent serious complications.
