When to see a doctor

By Mayo Clinic Staff

Seek emergency care if you experience:

  • Cough that produces bloody sputum
  • A fast heartbeat
  • Lightheadedness
  • Difficult or painful breathing
  • Chest pain or tightness
  • Pain extending to your shoulder, arm, back or jaw
  • Sudden weakness or numbness of your face, arm or leg
  • Sudden difficulty speaking or understanding speech (aphasia)
  • Sudden changes in your vision

Consult your doctor if you develop these signs or symptoms in an area on an arm or leg:

  • Swelling
  • Redness
  • Pain

Self-care measures

To reduce your risk of developing blood clots, try these tips:

  • Avoid sitting for long periods. If you travel by airplane, walk the aisle periodically. For long car trips, stop and walk around frequently.
  • Move. After you've had surgery or been on bed rest, the sooner you get up and move around, the better.
  • Drink plenty of fluids when traveling. Dehydration can contribute to the development of blood clots.
  • Change your lifestyle. Lose weight, lower high blood pressure, stop smoking and exercise regularly.
