A blood clot in the leg is often called deep vein thrombosis (DVT), a condition where a clot forms in a deep vein—usually in the calf or thigh. It can become dangerous if it travels to the lungs.
Here are 10 warning signs to know:
🦵 10 warning signs of a blood clot in the leg (DVT)
1. Swelling in one leg
- Usually sudden or noticeable on one side only
2. Pain or tenderness
- Often starts in the calf or thigh
- May feel like cramping or soreness
3. Warm skin on the affected area
- The skin may feel warmer than the other leg
4. Red or discolored skin
- Redness or a bluish/purple tone
5. Tightness in the leg
- Feeling of pressure or fullness
6. Pain that worsens when walking or standing
- Movement may increase discomfort
7. Visible enlarged veins
- Surface veins may look more prominent
8. Leg fatigue or heaviness
- One leg may feel unusually heavy or tired
9. Unexplained calf pain
- Especially if it persists without injury
10. Skin sensitivity
- Touching the area may feel painful or tender
🚨 Emergency warning (very important)
If a clot moves to the lungs, it can cause a pulmonary embolism, which is life-threatening.
Seek emergency help if you have:
- Sudden shortness of breath
- Chest pain (worse with breathing)
- Coughing blood
- Rapid heartbeat
- Dizziness or fainting
🧠 Who is at higher risk?
- Long periods of sitting (travel, bed rest)
- Recent surgery or injury
- Smoking
- Obesity
- Pregnancy
- Certain medical conditions (like cancer or clotting disorders)
💡 Key takeaway
- A DVT usually affects one leg only
- Symptoms often start subtly but should never be ignored
- Early treatment prevents serious complications
