What it is
Leg swelling (edema) happens when fluid collects in the tissues of the lower legs. It can have many causes, including problems with the veins that return blood to the heart, problems with the arteries that deliver blood to the legs, heart, kidney or lymphatic conditions, and some medications. Only a licensed clinician can determine the cause in any one person.
A leg ulcer is an open sore that is slow to heal, often taking weeks or longer. Venous ulcers are linked to veins that do not move blood upward efficiently, and they often appear near the ankle with swelling, skin darkening or itching. Arterial ulcers are linked to reduced blood flow to the legs and feet, and they can be painful, especially at rest or at night.
Because the causes differ, the approaches differ too. Some ulcers have more than one contributing factor, such as both vein and artery problems, or diabetes. This is why wound care specialists usually focus on finding out why the wound is not healing, not only on covering it.
How it’s traditionally been approached
Wound care for leg ulcers has traditionally started with a careful evaluation: a history, a look at the wound and surrounding skin, and often an assessment of circulation. This may include checking pulses or using painless tests that look at blood flow in the veins and arteries.
Compression therapy is a long-established approach for venous conditions. It uses wraps, bandages or specially fitted stockings to apply external pressure to the legs, which is thought to help support the veins and reduce swelling. Whether compression is appropriate depends on the person's circulation, so it is a decision for a licensed clinician after an evaluation, especially when arterial disease may be present.
Other tools specialists commonly use include wound cleaning and removal of non-healing tissue, dressings chosen for the wound's needs, attention to infection, and sometimes procedures on veins or arteries. Negative pressure wound therapy is well established for certain wounds. Skin substitutes and amniotic or placental grafts vary in FDA status, since most are regulated as minimally manipulated tissue rather than FDA-approved drugs, and coverage varies by product and payer. For further reading on amniotic products specifically, see amnioticdoctors.com, which is a separate resource and not affiliated with WoundKare. Hyperbaric oxygen therapy is FDA-cleared only for certain indications, such as some diabetic foot ulcers, radiation tissue injury and certain infections, and a provider can explain whether it applies.
How the right wound care specialist may help
The right vascular or wound specialist may help by identifying what is behind the swelling and the ulcer, which can shape the options that are discussed. A first visit generally includes questions about your health history, medications, mobility and how long the wound has been present, followed by an examination of both legs and possibly circulation testing.
A specialist may also explain what they see, whether the ulcer looks more venous, arterial or mixed, and what treatment options exist. They can talk through how compression works, whether it may be suitable for you, and what day-to-day care at home could involve. Outcomes and healing times vary from person to person, and nothing is guaranteed.
Helpful questions to ask a licensed provider: What is causing my wound? How would you describe its stage or severity? What are my treatment options and the reasons for each? What is the expected healing time? Is compression right for me, and how should it be worn? What does my insurance cover? And what signs should prompt me to call you sooner?
The whole-person view
Body, mind and stress affect one another. A wound that lingers can bring pain, poor sleep, worry, frustration and less activity, and those things can in turn make daily routines and self-care harder. Many people also feel isolated when a leg problem limits what they can do.
Looking after the whole person can be part of feeling supported. Some people explore body-based support such as Somatic Experiences to reconnect with how stress shows up physically, and others find talk therapy through Therapists.plus helpful for coping with the emotional weight of a long-term health issue. These are complements to, not replacements for, medical care, and every approach has value for different people.

Keep in mind
- Seek medical care promptly for any sign of infection: spreading redness, red streaking, increasing warmth or pain, pus, foul odor, fever or chills, or a wound that is quickly getting worse.
- Call 911 or go to the ER for heavy bleeding, exposed bone or tendon, signs of sepsis such as confusion or a rapid heartbeat with fever, or a deep or severely contaminated wound.
- Do not start compression or change how you care for a leg ulcer without a licensed clinician's guidance, because the right approach depends on your circulation and the cause of the wound.
- Licensed professionals should guide your care. If you are in emotional crisis, call or text 988, and use Providers.plus to find licensed providers.

What is wound care for non-healing leg ulcers?
Wound care for non-healing leg ulcers is a set of approaches a licensed clinician uses to find out why a leg sore is not closing and to support the healing environment. It commonly includes an evaluation of circulation, wound cleaning, dressings, and sometimes compression or procedures. The specific plan depends on the cause and is decided by your provider.
What is compression therapy for leg swelling?
Compression therapy uses wraps, bandages or fitted stockings to apply pressure to the legs, which is intended to support the veins and help reduce swelling. It is commonly used for venous conditions. Because it is not right for everyone, particularly if arterial blood flow is reduced, a licensed clinician should evaluate you first.
What kind of doctor treats leg ulcers?
Vascular specialists and wound care specialists commonly evaluate leg ulcers, and primary care clinicians, podiatrists and dermatologists may also be involved. Which provider is best depends on the cause of your ulcer and your health history. You can ask your primary care clinician for a referral or search licensed providers at Providers.plus.
What is the difference between a venous and an arterial ulcer?
A venous ulcer is linked to veins that do not return blood efficiently, while an arterial ulcer is linked to reduced blood flow delivered to the leg or foot. Venous ulcers often appear near the ankle with swelling, and arterial ulcers are often painful and may affect the toes or feet. Only a clinician can tell them apart, sometimes using circulation tests.
Is it safe to wear compression stockings if I have a leg ulcer?
It depends on the cause of your ulcer and your circulation, so you should ask a licensed provider before using compression. It is often used for venous ulcers but may be unsafe when arterial disease is significant. A provider can also show you how to apply it properly.
When should I see someone about a leg sore that won't heal?
See a licensed provider if a leg sore has not been improving, if swelling keeps returning, or if you are unsure of the cause. Seek care promptly for spreading redness, red streaking, pus, foul odor, increasing pain or warmth, fever or chills. Call 911 or go to the ER for heavy bleeding, exposed bone or tendon, or signs of sepsis.
