Symptoms
By Mayo Clinic staffIn about half of all cases, deep vein thrombosis occurs without any noticeable symptoms.
When deep vein thrombosis symptoms occur, they can include:
- Swelling in the affected leg, including swelling in your ankle and foot.
- Pain in your leg; this can include pain in your ankle and foot. The pain often starts in your calf and can feel like cramping or a charley horse.
- Warmth over the affected area.
- Changes in your skin color, such as turning pale, red or blue.
When to see a doctor
If you develop signs or symptoms of deep vein thrombosis, contact your doctor for guidance.
If you develop signs or symptoms of a pulmonary embolism — a life-threatening complication of deep vein thrombosis — seek medical attention immediately.
The warning signs of a pulmonary embolism include:
- Unexplained sudden onset of shortness of breath
- Chest pain or discomfort that worsens when you take a deep breath or when you cough
- Feeling lightheaded or dizzy, or fainting
- Rapid pulse
- Sweating
- Coughing up blood
- A sense of anxiety or nervousness
