Venous ulcers most often form around the ankles. Venous ulcers typically occur because of damage to the valves inside the leg veins. These valves control the blood pressure inside the veins.
Where are venous leg ulcers located?
They usually develop on the inside of the leg, just above the ankle. The symptoms of a venous leg ulcer include pain, itching and swelling in the affected leg. There may also be discoloured or hardened skin around the ulcer, and the sore may produce a foul-smelling discharge.
Where do arterial ulcers occur?
Arterial ulcers often form on the outer side of the ankle, feet, heels, or toes. They can form in other areas, too.
How do venous ulcers occur?
A venous leg ulcer can develop after a minor injury if there’s a problem with the circulation of blood in your leg veins. If this happens, pressure inside the veins increases. This constant high pressure can gradually damage the tiny blood vessels in your skin and make it fragile.
What does venous stasis ulcer look like?
Shallow sore with a red base, sometimes covered by yellow tissue. Unevenly shaped borders. Surrounding skin may be shiny, tight, warm or hot, and discolored.

What does the start of a leg ulcer look like?
Venous leg ulcers are sores that develop between your knee and ankle, but they typically form inside the leg near or around the ankle. They are large, shallow ulcers with uneven edges that drain or weep a lot. You’ll likely see swelling in your leg, with red, itchy skin around the wound.
Why do venous ulcers occur medially?
Venous Ulcers. Venous ulcers, also referred to as stasis, insufficiency or varicose ulcers, are the result of malfunctioning venous valves causing pressure in the veins to increase. These typically occur along the medial or lateral distal (lower) leg.
What causes venous leg ulcers?
What causes venous skin ulcers? Venous skin ulcers are caused by poor blood circulation from the legs, such as from venous insufficiency. Your veins have one-way valves that keep blood flowing toward the heart. In venous insufficiency, the valves are damaged, and blood backs up and pools in the vein.
What is an arterial leg ulcer?
An arterial ulcer is an ulcer due to inadequate blood supply to the affected area (ischaemia). Arterial ulcers tend to occur on the lower legs and feet, and may be acute, recurrent or chronic. Ulcers may have multiple contributing factors; these ‘mixed ulcers’ constitute roughly 15% of all leg ulcers.
What is the gaiter area?
Site & Appearance: Most venous ulcer occur in the “gaiter” area of the leg (i.e. area extending from just above the ankle to below the knee and tends to occur on both lateral and medial aspect of the leg), they are usually superficial with poorly defined margins.
What causes skin ulcers?
Skin ulcers are open round sores. They develop when blood can’t flow to an injury. Causes of poor blood flow include diabetes, atherosclerosis, pressure, and vein problems. Typically, skin ulcers affect the legs, but they can occur on the feet, hips, and back.
Why is my leg ulcer so painful?
When leg veins do not push blood back up to the heart as they should, the blood backs up (pools), creating extra pressure in the veins. If the condition is not treated, the increased pressure and excess fluid in the affected area can cause an open sore to form.
What antibiotics treat leg ulcers?
Choice of antibiotic
|Antibiotic[A]||Dosage and course length[B]|
|Doxycycline||200 mg on first day, then 100 mg once a day (can be increased to 200 mg daily) for 7 days in total|

How do you get rid of an ulcer on your leg?
Cleaning solutions can be applied to the ulcer using a swab (similar to a cotton bud), a syringe with a needle, or a spray canister. Ulcers can also be bathed in the cleaning solution, using a basin or bucket, or during a shower. Cleaning can cause discomfort, and may be painful.
