When to see a doctor

By Mayo Clinic staff

Seek emergency care if you experience:

  • Shortness of breath
  • Pressure, fullness or a squeezing pain in the center of your chest lasting more than a few minutes
  • Pain extending to your shoulder, arm, back, teeth or jaw
  • Sudden weakness or numbness of your face, arm or leg
  • Sudden difficulty speaking or understanding speech (aphasia)
  • Sudden blurred, double or decreased vision

Consult your doctor if you develop:

  • Swelling, redness, numbness or pain in a leg or arm
  • Intense burning or throbbing on your palms or soles
  • Chronic headache or dizziness

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 car trips, stop and walk around frequently.
  • Move. After you've had surgery or been on bed rest, the sooner you move, the better.
  • Change your lifestyle. Lose weight, lower high blood pressure, stop smoking and exercise regularly.
