If leg swelling because of chronic venous insufficiency isn't controlled, an open wound (ulcer) can form. Ulcers vary in size and shape. But they usually appear on the inside of the ankle.
Treating an ulcer
- Wear compression bandages or stockings every day. This is the most important treatment for venous ulcers. It reduces swelling and helps the ulcer heal. Ask your doctor which type is best for you.
- See your doctor regularly. Ulcers need frequent medical care. Special dressings may be applied. You may be given antibiotics to fight infection.
- Your doctor may prescribe medicines, such as aspirin or pentoxifylline, to help the ulcer heal.
- Raise (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.
When to contact your doctor
Contact your doctor right away if you have any of the following:
- More pain
- Fever of
100.4°F (38°C) or higher, or as directed by your doctor - The area around the ulcer becomes red, sore, or both
- The ulcer oozes discolored fluid or smells bad
- Swelling increases suddenly or the dressing feels tight
