What do swollen ankles feel like with heart failure?

When the heart is not pumping effectively, pressure can build in the veins and fluid can move into the tissues. The ankles and feet may look puffy, feel stretched, and leave shoes or sock marks. Swelling often affects both legs and may be more noticeable later in the day or after standing.

Heart-failure-related swelling may occur with breathlessness, reduced ability to exercise, tiredness, a cough, or a quick change in body fluid. These features can also have other causes, so ankle swelling does not diagnose heart failure by itself. A clinician may review the heart, lungs, medicines, blood pressure, and fluid balance.

If you have known heart failure, follow your agreed medicine, salt, fluid, and weight-monitoring plan. Tell your heart-failure team about increasing swelling, tighter shoes, worsening breathlessness, or a noticeable change from your usual pattern.

Resting with your legs raised may reduce discomfort, but do not change diuretics or restrict fluids unless your clinician has given you a clear plan. Keep a record of symptoms, daily activity, and any changes that could help your review.

Call emergency services for severe breathlessness at rest, chest pain, fainting, new confusion, blue or grey lips, or difficulty speaking because of breathlessness. Sit upright while waiting and follow any emergency plan given by your care team.

Seek prompt medical advice if swelling is increasing, breathlessness is worse when lying down, you wake gasping, or your usual activity suddenly becomes harder. Early review can identify fluid build-up before it becomes severe.

Is my ankle swelling consistent with fluid retention or another cause? What changes in breathing or swelling should I report the same day? How should I monitor weight and fluid, and when should my medicine plan be reviewed?
