If your skin looks red, bluish, or unusually pale in a certain area, it may signal restricted blood flow caused by a clot.
4. Warmth in the Affected Area
Blood clots often cause localized warmth over the skin where the clot is lodged. If one leg feels warmer than the other, it’s a red flag.
5. Sudden Shortness of Breath
A clot that travels to the lungs (pulmonary embolism) can cause difficulty breathing, rapid heartbeat, or chest tightness. This is a medical emergency—seek help immediately.
6. Chest Pain or Pressure
Clots in the heart or lungs may cause sharp chest pain, heaviness, or pressure that mimics a heart attack. If chest pain comes with dizziness or sweating, call emergency services right away.
7. Fast Heartbeat or Lightheadedness
When oxygen supply drops due to a clot, your heart works harder. This may lead to rapid heartbeat, dizziness, or fainting. Don’t brush it off.
8. Persistent Cough (Sometimes With Blood)
A clot in the lungs can trigger a chronic cough, often producing pink or blood-streaked mucus. This is another emergency sign that requires urgent care.
