What Is a Foot Ulcer?
A foot ulcer is an open sore or wound that develops on the foot, often due to poor blood circulation, nerve damage, repetitive trauma, or a combination of these issues. These ulcers can range from minor skin erosions to deep wounds that may reach tendons or bones, increasing the risk of severe infection. While they often appear on the bottom of the foot or near pressure points, they can occur anywhere. Prompt medical attention is essential—without proper care, foot ulcers can lead to serious infections, hospitalization, and even amputation.
Types of Foot Ulcers
Foot ulcers are generally classified into several categories, depending on their root cause:
- Neuropathic ulcers: These are caused by nerve damage, commonly seen in people with diabetes. Since they often lack sensation, these ulcers may go unnoticed until they become severe.
- Ischemic ulcers: Caused by insufficient blood flow, typically in individuals with peripheral artery disease (PAD). These ulcers may be painful and slow to heal.
- Neuroischemic ulcers: Result from a combination of neuropathy and ischemia. They are often complex and require multidisciplinary care.
- Traumatic ulcers: Develop from physical injuries, including cuts, burns, or blisters caused by tight or ill-fitting shoes. Even minor trauma can lead to serious wounds in at-risk individuals.
What Causes Foot Ulcers?
Foot ulcers develop from a combination of physical stress and underlying medical conditions. Common causes include:
- Repetitive pressure or friction on the skin
- Poor circulation due to PAD or heart disease
- Nerve damage (neuropathy), often associated with diabetes
- Improper footwear that causes blisters, sores, or persistent pressure
- Injuries such as cuts, burns, or puncture wounds that go untreated
- Dry skin or calluses that crack open and become infected
What Are the Risk Factors and Complications of Foot Ulcers?
Some individuals are more prone to developing foot ulcers. High-risk groups include:
- People with diabetes or pre-diabetes
- Individuals with a history of foot ulcers, infections, or amputations
- Smokers and those with vascular disease
- Patients with kidney disease, immune system disorders, or other chronic illnesses
- People who frequently walk barefoot or wear shoes that don’t fit properly
Potential complications include:
- Local infections, such as cellulitis
- Deep infections, including osteomyelitis (bone infection)
- Gangrene, which may require amputation
- Delayed or impaired wound healing
- Recurrence of ulcers after healing
- Reduced mobility and quality of life
What Are the Symptoms of Foot Ulcers?
The signs of a foot ulcer can vary based on its severity and underlying cause, but commonly include:
- A visible open sore or wound, especially on the bottom of the foot
- Redness, warmth, or swelling around the ulcer
- Drainage or pus, which may stain socks or shoes
- A foul odor coming from the wound
- Tenderness or pain, particularly when walking or putting pressure on the foot
- Numbness or tingling, particularly in diabetic patients with nerve damage
It’s important not to ignore even minor symptoms. Early detection and care can prevent a small problem from becoming a serious complication.
How Do You Diagnose Foot Ulcers?
Diagnosing a foot ulcer involves a comprehensive evaluation to understand the wound’s cause, severity, and any related complications. Your podiatrist may perform:
- A detailed physical examination to assess wound size, depth, and signs of infection
- Wound cultures to identify bacteria and guide antibiotic treatment
- Blood tests to detect diabetes, infection, or underlying conditions
- Imaging (X-ray, MRI) to check for bone involvement or foreign bodies
- Vascular studies to evaluate circulation and identify blockages or narrowing in blood vessels
Early and accurate diagnosis helps ensure effective treatment and better long-term outcomes.
How Do You Treat Foot Ulcers?
Treatment for foot ulcers is highly individualized and depends on several factors, including the ulcer’s cause, depth, size, location, and overall health status of the patient. A holistic treatment plan may include wound care, infection control, offloading strategies, and circulation support.
Types of Foot Ulcer Treatment
- Wound debridement: This involves the removal of dead or infected tissue to stimulate healthy tissue growth and improve healing.
- Infection management: Treatment may involve topical or oral antibiotics to fight bacterial infections and prevent complications.
- Offloading techniques: Special footwear, braces, or custom orthotic devices reduce pressure on the wound to promote healing.
- Advanced wound dressings: Dressings designed to keep the wound moist and protected may include hydrogels, foams, or hydrocolloids.
- Surgical interventions: In more advanced cases, surgery may be required to remove infected tissue, correct deformities, or restore blood flow.
- Adjunctive therapies: Options like negative pressure wound therapy or hyperbaric oxygen therapy may also be recommended for complex or chronic wounds.
Benefits and Risks of Foot Ulcer Treatment
Benefits:
- Accelerates wound healing and tissue regeneration
- Prevents infection and serious complications
- Minimizes the need for amputation or long-term hospitalization
- Restores mobility and enhances overall well-being
- Reduces recurrence when paired with proper foot care
Risks:
- Possibility of ulcer recurrence if preventive steps aren’t followed
- Side effects from medications or dressings
- Infection if the wound isn’t properly managed
- Delayed healing in patients with poor circulation or immune issues
- Surgical risks, including bleeding, scarring, or poor outcomes in high-risk patients

Frequently Asked Questions
How does a diabetic ulcer start?
A diabetic ulcer often starts with a small, unnoticed injury—like a blister, cut, or sore—usually on the bottom of the foot. Due to nerve damage (neuropathy), many people with diabetes can’t feel the injury. Poor circulation slows healing, allowing the wound to worsen over time. If not properly cared for, the wound can develop into an open ulcer that is vulnerable to infection.
Can you walk on a foot ulcer?
It’s strongly discouraged to walk normally on a foot ulcer. Pressure from walking can worsen the ulcer, delay healing, and increase the risk of infection. Podiatrists often recommend “offloading” techniques such as using a walking boot, crutches, or custom orthotics to keep weight off the affected area. Proper offloading is crucial for healing and preventing further damage.
How to clean a foot ulcer?
Cleaning a foot ulcer should always be done under the guidance of a healthcare provider. Typically, the wound is gently rinsed with sterile saline or clean water to remove debris. Avoid using hydrogen peroxide or harsh antiseptics, as they can damage healthy tissue. After cleaning, the ulcer should be covered with a sterile, moisture-retentive dressing. Regular cleaning and dressing changes—done properly—help lower the risk of infection and promote healing.
How can I speed up the healing of a foot ulcer?
To help a foot ulcer heal faster:
- Keep pressure off the ulcer (offloading)
- Follow your wound care plan consistently
- Manage underlying conditions like diabetes or vascular disease
- Keep blood sugar levels under control
- Avoid smoking, which restricts circulation
- Attend all follow-up appointments for monitoring and treatment adjustments
Healing is a process, but with proper care and early intervention, most foot ulcers can improve significantly and avoid serious complications.
