If leg swelling because of chronic venous insufficiency isn’t controlled, an open wound (ulcer) can form. Although ulcers vary in size and shape, they usually appear on the inside of the ankle.
Visit your healthcare provider. Ulcers need frequent medical care. Special dressings may be applied. You may be given antibiotics to fight infection.
Your healthcare provider may prescribe medicines, such as aspirin or pentoxifylline, to help the ulcer heal.
Your healthcare provider may prescribe compression hose to help with the swelling.
Elevate your legs often to reduce swelling. The ulcer needs oxygen-rich blood to heal. This blood can’t reach the ulcer until swelling is reduced.
Seek immediate medical attention if:
You have an increase in pain
You develop a fever of 100.4°F (38°C) or higher, or as directed by your healthcare provider
The area around the ulcer becomes red, tender, or both
The ulcer oozes discolored fluid or smells bad
Swelling increases suddenly or the dressing feels tight
