Does varicose veins cause swollen ankles?

Veins in the legs use valves to help blood travel back towards the heart. In varicose veins, those valves may not close effectively, allowing blood to pool in the lower leg. Fluid can then move into nearby tissues, making the ankles look puffy or feel tight. Swelling may become more noticeable later in the day and improve after resting with the legs raised. It can occur with aching, heaviness, itching, or visible twisted veins, but ankle swelling also has causes unrelated to veins.

Arrange a routine clinical review if swelling keeps returning, is affecting daily activity, or comes with skin changes around the ankles. A clinician can examine the veins and consider other contributors such as medicines, heart, kidney, or liver problems. While waiting, gentle walking, avoiding long periods in the same position, and raising the legs when resting may ease pooling. Do not start compression stockings without advice if you have poor circulation, severe leg pain, or uncertain cause of swelling.

Seek urgent medical assessment for sudden swelling of one leg, new calf pain, warmth, redness, chest pain, shortness of breath, or coughing blood. These symptoms need prompt assessment because they can occur with a blood clot or another urgent illness. Get same-day advice if swelling rapidly worsens, a vein bleeds, or the skin becomes broken, darkened, or painful.

Ask whether the pattern of swelling fits a vein problem, whether an ultrasound examination is appropriate, and whether compression is suitable for you. Mention when the swelling starts, whether both ankles are affected, any medicines you take, and any past clot, surgery, pregnancy, or circulation problem.
