Blood pressure and swollen ankles

Fluid can collect around the ankles when the heart, kidneys, or veins are not moving blood and fluid efficiently. Heart failure and chronic kidney disease are examples of conditions that may cause swelling. Varicose veins, prolonged sitting or standing, obesity, injury, and some medicines can also contribute. Swelling in one ankle, sudden swelling, or swelling with pain may have a different explanation from swelling in both ankles.

Arrange a clinical review if swelling persists, returns, or appears after a blood-pressure medicine change. Note whether it affects one or both ankles, whether it is worse by evening, and whether pressing the skin leaves a temporary dent. Keep taking prescribed medicine unless the prescriber advises otherwise. Gentle movement and raising the legs while resting may help, but avoid changing salt or fluid intake without advice if you have heart or kidney problems.

Seek emergency help for sudden breathlessness, chest pain, coughing blood, fainting, or rapidly worsening swelling. Get urgent assessment for one-sided swelling with warmth or pain, blue or cold skin, or swelling accompanied by severe headache or a marked change in blood pressure.

Ask whether your medicine could contribute, whether you need kidney or heart checks, and what changes in swelling, breathing, weight, or blood pressure should prompt contact.
