Skin ulcers are open wounds that develop when blood flow to certain areas of the body is compromised, making it difficult for the skin to heal properly and leaving people vulnerable to infection and serious complications that can affect their quality of life.

How Doctors Approach the Challenge of Healing Stubborn Wounds

When an area of skin breaks down and fails to heal on its own, medical teams face a complex challenge that requires careful attention and a strategic approach. The main goal of treating skin ulcers is to promote healing, prevent infection, control pain, and stop the problem from getting worse. Treatment success depends heavily on understanding what type of ulcer a person has, what caused it in the first place, and the individual’s overall health situation.^[1]

The path to healing is rarely simple. What works for one person may not work for another, because skin ulcers arise from different underlying problems and each patient brings their own unique health circumstances to the table. For instance, someone with diabetes will need a very different treatment plan than someone who developed an ulcer from staying in bed too long. Age, nutrition, mobility, and other existing medical conditions all play a role in determining which treatments will be most effective.^[2]

Medical professionals rely on established treatment guidelines that have been tested and proven effective over many years. These standard approaches form the foundation of care. At the same time, researchers are actively investigating new therapies and testing them in clinical trials, searching for better ways to speed healing, reduce pain, and prevent ulcers from coming back. This combination of proven treatments and innovative research offers hope for better outcomes, especially for people whose ulcers have been slow to heal with conventional methods.^[1]

The treatment journey often involves multiple healthcare professionals working together. A primary care doctor may coordinate overall care, while wound care specialists handle the day-to-day management of the ulcer itself. Nurses play a crucial role in teaching patients and families how to care for wounds at home. Physical therapists help people move safely and maintain circulation. Dietitians ensure patients are eating foods that support healing. This team approach recognizes that healing a stubborn wound requires attention to many different aspects of a person’s health at once.^[12]

Proven Medical Treatments That Form the Core of Ulcer Care

The cornerstone of treating most skin ulcers involves a combination of strategies aimed at improving blood flow, protecting the wound, and creating the best possible environment for healing. The specific approach varies depending on the type of ulcer, but certain principles apply across the board.

For venous skin ulcers, which occur when blood pools in the legs due to faulty valves in the veins, compression therapy is the primary treatment. Healthcare professionals apply special bandages or stockings that squeeze the leg in a specific pattern, encouraging blood to flow upward toward the heart instead of pooling in the lower legs. These compression bandages come in different types and strengths, and must be applied by trained staff to work properly and avoid causing harm. The bandages typically need to be changed one to three times per week when dressings are replaced.^[10]

When compression therapy first begins, many people find it uncomfortable or even painful, especially if their ulcer is in an active, unhealthy state. Doctors usually prescribe pain medication such as paracetamol to help manage this initial discomfort. As the ulcer begins to heal, the pain typically lessens. Patients are advised to keep their legs elevated whenever possible, ideally with their feet higher than their hips. This simple position change helps reduce swelling by using gravity to drain excess fluid from the legs. Many people find it helpful to prop their legs on pillows while lying down, aiming for three to four sessions of 30 minutes each day.^[7]

The duration of compression therapy extends beyond the initial healing period. Even after an ulcer has closed, patients need to continue wearing compression stockings daily, removing them only for bathing and sleeping. This ongoing compression helps prevent new ulcers from forming, which is particularly important because venous ulcers have a strong tendency to come back. With appropriate treatment including compression, venous leg ulcers often heal within six months, though some may take longer depending on their size and severity.^[10]

Cleaning and dressing the ulcer properly is essential for all types of skin ulcers. The first step involves removing any dead tissue from the wound through a process called debridement. This dead tissue can harbor bacteria and prevent healthy tissue from growing. Healthcare professionals may remove it using various methods, from gentle washing to surgical removal in more severe cases. Once the dead tissue is cleared away, the wound is thoroughly cleaned and dried before applying an appropriate dressing.^[10]

The choice of dressing depends on many factors, including the ulcer’s size, depth, location, and how much fluid it produces. A simple, non-stick dressing is often used initially. The dressing serves multiple purposes: it protects the wound from further injury, keeps it moist to promote healing, and prevents bacteria from entering. Different types of dressings include films, gauze, gels, foams, and specialized materials designed for specific wound conditions. Many patients learn to change their own dressings under a nurse’s supervision, which helps them take an active role in their healing.^[12]

For pressure ulcers, also called bedsores or decubitus ulcers, the primary treatment focuses on relieving pressure on the affected area. This means using special cushions, mattress pads, or positioning devices to keep pressure off the wound. People who are bedridden or use wheelchairs need to change positions frequently—ideally every 15 minutes for wheelchair users and every two hours for those in bed. These frequent position changes allow blood to flow back into areas that were compressed, delivering the oxygen and nutrients needed for healing.^[12]

Various pressure-relieving devices are available, including water-filled or air-filled cushions, foam pads, and specialized mattresses. The choice depends on the person’s specific situation, the location and severity of the ulcer, and whether they spend more time in bed or in a wheelchair. Healthcare providers work with patients and families to determine which type of support surface will be most effective and practical for their circumstances.^[19]

When ulcers become infected, antibiotic therapy becomes necessary. Infections are serious complications that can spread throughout the body if not treated promptly. Signs of infection include increased pain, swelling, warmth, redness spreading away from the wound, pus drainage, foul odor, and fever. Healthcare providers may prescribe oral antibiotics for milder infections or intravenous antibiotics for more serious cases. The specific antibiotic chosen depends on what bacteria are causing the infection, which can be determined through laboratory testing of wound samples.^[11]

The approach to antibiotic treatment requires careful consideration. Healthcare professionals must balance the need to treat infection effectively against the risk of antibiotic resistance, which occurs when bacteria evolve to survive despite antibiotic treatment. This is why doctors take wound cultures to identify exactly which bacteria are present, allowing them to select the most appropriate antibiotic rather than prescribing broad-spectrum drugs unnecessarily. Treatment duration varies but typically continues until clear signs of infection have resolved.^[11]

Pain management is another crucial component of ulcer treatment. Many people experience constant pain that interferes with sleep, daily activities, and quality of life. Pain medications ranging from over-the-counter options like paracetamol to stronger prescription drugs may be needed. Beyond medication, other approaches can help, such as keeping the wound properly dressed, avoiding activities that aggravate the area, and using relaxation techniques. Some patients benefit from specialized pain clinics that offer comprehensive pain management strategies.^[3]

Nutritional support plays a vital but sometimes overlooked role in ulcer healing. The body needs adequate protein, calories, vitamins, and minerals to repair damaged tissue and fight infection. Research has shown that people with poor nutrition, particularly insufficient protein intake, experience slower healing. Healthcare providers may recommend dietary changes, nutritional supplements, or work with dietitians to ensure patients are getting what they need. Good protein sources include fish, chicken, eggs, dairy products, beans, and soy products.^[17]

Some patients develop additional skin problems around their ulcers. Venous eczema can cause the skin near the ulcer to become dry, scaly, and intensely itchy. This condition is treated with moisturizers called emollients and sometimes mild corticosteroid creams or ointments. It’s important not to scratch itchy skin, as this can cause breaks in the skin that lead to additional ulcers or infection. Some people develop allergic reactions to dressings or creams used to treat their ulcers, requiring allergy testing and switching to different products.^[10]

For ulcers that don’t heal with standard treatments, more advanced options may be considered. Skin grafting involves taking healthy skin from another part of the patient’s body and placing it over the ulcer to help it close. This procedure is typically reserved for deep or stubborn ulcers that haven’t responded to other treatments. Vein surgery may be recommended for people with venous ulcers to correct the underlying valve problems that cause blood to pool, helping prevent ulcers from coming back after they heal.^[7]

Innovative Therapies Being Investigated in Research Studies

While standard treatments work well for many people, researchers continue searching for new approaches that might heal ulcers faster, reduce pain, or help people whose ulcers haven’t responded to conventional treatment. These experimental therapies are tested in clinical trials, which are carefully designed research studies that evaluate whether new treatments are safe and effective.

One promising area of investigation involves hyperbaric oxygen therapy (HBO). This treatment places patients in a special chamber filled with highly concentrated oxygen—much more than what we breathe in normal air. The theory is that flooding the body with extra oxygen helps damaged tissues heal faster because oxygen is essential for wound healing and fighting infection. Patients typically receive treatments five days per week for several weeks.^[17]

Clinical trials have produced encouraging results for HBO therapy. A double-blind trial found that patients with chronic leg ulcers who were not diabetic experienced significantly improved healing when they received systemic HBO treatments for six weeks compared to those who didn’t receive this therapy. Other studies have looked at diabetic patients with foot ulcers or gangrene and found that HBO therapy helped prevent amputation of affected limbs—a devastating outcome that significantly impacts quality of life.^[17]

There are different ways to deliver HBO therapy. Systemic treatment involves the whole body in a pressurized chamber, while topical application uses a balloon-like chamber around just the affected body part. Research results have been mixed regarding which approach works better, with some controlled trials showing positive results for topical HBO and others showing no significant benefit. More research is needed to determine which patients might benefit most from this therapy and what the optimal treatment protocol should be.^[17]

Another innovative approach uses electrical stimulation applied to the skin around the ulcer. Scientists believe that controlled electrical currents may have several biological effects that accelerate healing, such as improving blood flow, reducing inflammation, and stimulating cell growth. Various techniques have been studied, including low-voltage galvanic current, high-voltage pulsed current, and pulsed high-frequency electromagnetic therapy. Several controlled and double-blind trials have shown positive results, though this treatment is not yet widely available in standard clinical practice.^[17]

Researchers are also investigating nutritional interventions that go beyond basic dietary advice. Some studies have examined whether specific vitamin and mineral supplements can speed healing. Vitamin C, which plays a crucial role in forming collagen (a protein essential for wound healing), has been studied at doses of 1,000 mg daily. Zinc, another important nutrient for tissue growth and immune function, has been tested in clinical trials, often at doses of 50 mg or more per day. Because zinc can interfere with copper absorption, supplementation usually includes 1 to 3 mg of copper to prevent deficiency.^[17]

While these nutritional supplements show promise in research, it’s important to note that more is not always better. Taking very high doses of vitamins or minerals without medical supervision can cause side effects or interact with other medications. Anyone interested in nutritional supplements should discuss this with their healthcare provider, who can evaluate whether supplementation is appropriate based on their individual health status and current medications.^[17]

Advanced wound dressings represent another area of active research. Scientists are developing “smart” dressings that do more than simply cover the wound. Some experimental dressings release medications slowly over time, deliver growth factors that stimulate healing, or change color to warn when infection is developing. Others incorporate materials like honey, silver, or specialized synthetic compounds designed to kill bacteria or promote tissue growth. Many of these products are in various stages of clinical testing to determine their safety and effectiveness.^[18]

Clinical trials studying new ulcer treatments typically progress through several phases. Phase I trials focus primarily on safety, testing the new treatment in a small number of people to see if it causes harmful side effects and to determine appropriate dosing. Phase II trials enroll more patients and begin looking at whether the treatment actually helps heal ulcers. Phase III trials are larger studies that compare the new treatment directly to standard treatment to see if it works better, worse, or about the same. Only treatments that successfully pass through all these phases typically become available for routine use.^[11]

Gene therapy and other molecular approaches are being explored in laboratory studies, though most haven’t yet reached human clinical trials for skin ulcers. These futuristic treatments aim to directly address the molecular problems that prevent ulcers from healing, such as delivering genes that stimulate blood vessel growth or produce growth factors. While promising in theory, these approaches must prove safe and effective in extensive testing before becoming treatment options for patients.^[11]
