THE SHORT ANSWER

A non-healing wound is treated by finding and fixing what is blocking healing: removing dead or infected tissue (debridement), controlling infection, keeping the wound bed properly moist and managing conditions such as diabetes or poor circulation. When standard care is not enough, options such as negative pressure (wound VAC) therapy, skin substitutes or grafts and hyperbaric oxygen may help.

What Is a Non-Healing Wound?

A non-healing, or chronic, wound is one that does not move through the normal stages of healing, typically within about three to four weeks. Acute wounds, such as a small cut or a healthy surgical incision, close fairly quickly. Chronic wounds stay open, become infected or heal very slowly, sometimes for months or even years without the right treatment.

MedlinePlus describes a wound as non-healing if it has not started to heal within 2 weeks or has not completely healed within 6 weeks. Chronic wounds can appear anywhere on the body, but they are most common on the feet, the legs and pressure points such as the heels, hips and tailbone.

Common types include:

Diabetic foot ulcers
Pressure sores (pressure ulcers or pressure injuries)
Ulcers linked to poor blood flow or swollen legs
Surgical wounds that open or heal poorly

Why Do Some Wounds Stop Healing?

Wounds stop healing when something keeps blood, oxygen and the body’s repair cells from doing their job. Chronic wounds do not happen without a reason, and finding that reason is the most important part of treatment. Common causes include:

Diabetes: high blood sugar can damage nerves and blood vessels, reducing both circulation and the ability to feel an injury.
Poor circulation: conditions such as peripheral artery disease reduce blood flow to the wound.
Infection: bacteria slow healing and keep the wound inflamed.
Pressure: limited mobility can lead to pressure ulcers, especially in older adults and people who are bedbound.
Surgical complications: a postoperative wound can heal poorly because of tissue damage or infection.

Other factors can add to the problem. MedlinePlus lists obesity, older age, smoking, heavy alcohol use, stress and certain medicines, such as corticosteroids, NSAIDs and some chemotherapy drugs, among the things that can slow healing. A weakened immune system can also delay recovery.

What Are the Signs a Wound Is Not Healing Properly?

The main sign is a wound that is not getting smaller or looking healthier week by week. Watch for these red flags:

The wound is still open after 2 to 3 weeks
Pain, redness or swelling is increasing instead of easing
A foul odor, pus or other discharge
Dark or black tissue in or around the wound (necrosis)
Fever, chills or feeling generally unwell, which can signal infection spreading through the body

See a healthcare provider if your wound has not improved after about 2 weeks, if you notice signs of infection, or if the wound gets worse or more painful. If you have diabetes, have any foot wound checked, no matter how small. Nerve damage can hide pain, so a minor blister or cut can become a serious ulcer before it hurts. Early care is easier and more effective than treating a wound after it has escalated.

When Is a Non-Healing Wound an Emergency?

A wound becomes an emergency when infection is spreading quickly or tissue is dying. Go to the emergency room or call 911 if you have:

Redness, warmth or swelling that is spreading fast, or red streaks moving away from the wound
Fever, chills, confusion, a racing heart or feeling very sick
Skin that turns black or gray, especially with a bad smell
Severe pain that is out of proportion to how the wound looks

Left untreated, a chronic wound can lead to serious complications:

Infection of the skin and soft tissue (cellulitis), a pocket of pus (abscess) or the bone (osteomyelitis)
Tissue death (gangrene) from prolonged lack of blood flow
Amputation, especially in people with diabetes and foot ulcers
Sepsis, a life-threatening reaction when infection spreads into the bloodstream

Prompt, focused care can prevent many of these outcomes and support a full recovery.

How Do Surgeons Evaluate a Wound That Will Not Heal?

Surgeons evaluate a chronic wound by looking at the wound itself and then asking why it has not healed. Treating only the surface rarely works if the underlying cause is missed.

The wound: its size, depth and location, the color of the tissue in the base, and whether there is drainage, odor or exposed deeper structures.
Infection: redness, warmth, swelling and pus around the wound, and signs that infection may have reached deeper tissue or bone.
Circulation: whether enough blood is reaching the area, since a wound cannot heal without it.
Underlying conditions: diabetes and blood sugar control, vascular disease, immune problems, nutrition, smoking and the medicines you take.
Pressure and swelling: whether the wound sits on a pressure point or in a swollen leg.

Depending on what the exam shows, further tests may be ordered to look for infection or check blood flow. The answers decide the plan: a wound with poor circulation, for example, needs that problem addressed before it can close.

How Is a Non-Healing Wound Treated?

Treatment starts with a thorough evaluation and then focuses on four basics: clearing unhealthy tissue, controlling infection, managing moisture and fixing the underlying problem.

Debridement: removing dead or infected tissue so healthy new tissue can grow. This can be done surgically or with other methods, such as enzymes, special dressings or irrigation.
Infection control: depending on the wound, your doctor may recommend topical or oral antibiotics to stop bacteria from spreading and reduce inflammation.
Moisture balance: the wound bed should stay moist enough to heal, but not so wet that it breaks down the surrounding skin or encourages bacteria. Dressings such as gels, foams, gauze and films are chosen for this reason.
Managing underlying conditions: controlling diabetes, treating vascular disease or immune problems, relieving pressure and reducing swelling, for example with compression stockings when appropriate.

Addressing the root cause, not just the surface of the wound, is what most improves healing and lowers the risk of complications. For wounds after an operation, see our guide to post-operative care.

What Advanced Wound Care Options Are Available?

When standard wound care is not enough, advanced treatments can help a wound close and lower the risk of further damage. The right option depends on the wound’s cause, size and location.

Negative pressure wound therapy (wound VAC): a sealed dressing connected to a gentle vacuum removes excess fluid and increases blood flow to the area, which can help the wound close faster and reduce infection risk.
Skin substitutes and grafts: used for wounds with large areas of tissue loss. These may be synthetic or biological materials, or the patient’s own skin moved over the wound, and they protect the wound and stimulate tissue growth.
Hyperbaric oxygen therapy (HBOT): breathing 100% oxygen in a pressurized chamber to raise the oxygen supply to damaged tissue. It helps some wounds heal faster and is used for selected cases.
Biological dressings and growth factor therapy: dressings or products containing growth factors that help wound-healing cells grow. Some products are marketed as containing stem cells; ask your care team what evidence supports any specific product.

These therapies are typically available in specialized wound care clinics or surgical centers that have the right equipment and experience.

How Can I Care for a Chronic Wound at Home?

Home care matters as much as clinic visits, because the wound spends most of its healing time between appointments. Follow your provider’s instructions closely:

Keep the wound and dressing clean, and keep the dressing dry on the outside unless you are told otherwise
Change dressings on schedule with clean hands and sterile supplies
Do not smoke; tobacco narrows blood vessels and delays healing
Limit alcohol
If you have diabetes, keep your blood sugar under control
Drink enough fluids and eat a nutrient-rich, high-protein diet to give your body the building blocks for new tissue
Keep pressure off the wound and stay as mobile as your care team advises

If you have diabetes, check your feet every day, including between the toes, and use a mirror or ask someone to help if bending is hard. Combining professional treatment with careful home care gives a chronic wound the best chance of healing completely and staying healed.

Which changes mean I should call the office or go to the ER?

Frequently Asked Questions

How long is too long for a wound to heal?

A wound that has not started to heal within about 2 weeks, or is still open after 3 to 4 weeks, deserves a medical evaluation. MedlinePlus considers a wound non-healing if it is not fully healed within 6 weeks.

Should a chronic wound be kept moist or dry?

The wound bed generally heals best when it is kept moist but not soaking wet, while the outside of the dressing and the surrounding skin stay clean and dry. Follow the dressing plan your provider gives you, because the right balance depends on the wound.

Why do people with diabetes get wounds that will not heal?

High blood sugar can damage nerves and blood vessels, so injuries may go unnoticed and get less blood flow. That is why any foot wound in a person with diabetes should be checked promptly.

What is a wound VAC?

A wound VAC is negative pressure wound therapy: a sealed dressing attached to a gentle vacuum that removes excess fluid and increases blood flow, helping some wounds close faster. Learn more on our wound care page.

Can a non-healing wound lead to amputation?

It can, particularly a diabetic foot ulcer that becomes infected or develops gangrene. Early evaluation and treatment are the best ways to lower that risk.

Key Takeaway

A wound that will not heal is usually a sign of an underlying problem such as diabetes, poor circulation, infection or pressure. Treatment combines debridement, infection control, the right dressings and care for the root cause, with advanced options when needed. Spreading redness, fever or blackened tissue needs emergency care.
