[39F] With sudden onset of unilateral ankle swelling

What might be happening

Based on your symptoms, here are a few possibilities:

• Deep Vein Thrombosis (DVT): This is a blood clot in a deep vein, often in your leg. It can cause swelling, but it's usually accompanied by pain and redness.

  • Treatment typically involves medications to thin your blood and prevent the clot from getting bigger.

• Heart Failure: Given your history of heart disease, heart failure is a possibility. This condition occurs when your heart doesn't pump blood as well as it should, and it can cause swelling in your legs and ankles.

  • Treatment usually involves a combination of lifestyle changes and medications to help your heart pump more efficiently.

• Kidney Disease: Your kidneys remove waste and extra fluid from your body. If they aren't working properly, that fluid can build up and cause swelling in your ankles.

  • Treatment depends on the underlying cause of the kidney disease, but it often involves medications and dietary changes.

What you can do

You should seek medical attention as soon as possible, as these conditions can be serious. In the meantime, try to keep your leg elevated and avoid standing for long periods of time.

What you should look out for

If you notice any of the following, you should seek medical attention immediately:

• Increased swelling
• Pain in your leg
• Chest pain or discomfort
• Difficulty breathing
