SECTION 3

When should I seek help?

Call 911 for leg swelling with sudden breathlessness, chest pain, fainting, or coughing up blood. A blood clot in the lungs or another emergency may be present.

Seek prompt assessment

New swelling in one leg, especially with pain, warmth, or redness, needs urgent evaluation for a clot or infection. Do not massage a newly swollen, painful leg.

Contact your clinician for persistent or worsening swelling, skin sores, or rapid weight gain. If you have heart failure, follow your action plan for changes in weight, swelling, or breathing.
