When a Wound Won’t Heal — What You Need to Know

Most minor wounds — cuts, scrapes, small ulcers — heal within a few weeks. But for millions of Americans, wounds simply don’t heal on their own. These are called chronic wounds, and they’re more than just a nuisance. Left untreated, they can lead to serious infection, bone damage, and in severe cases, amputation. If you or a loved one has a wound that just won’t close, understanding why is the first step toward healing.

What Is a Chronic Wound?

A wound is considered chronic when it fails to heal in an orderly and timely fashion — typically defined as not showing significant improvement after 4-6 weeks of standard care. The most common types of chronic wounds are: venous leg ulcers (caused by poor venous circulation), diabetic foot ulcers (caused by nerve damage and poor blood flow from diabetes), pressure ulcers/bedsores (caused by prolonged pressure on the skin), arterial ulcers (caused by poor arterial blood supply), and non-healing surgical wounds.

Why Do Some Wounds Fail to Heal?

Normal wound healing requires adequate blood flow, a healthy immune response, proper nutrition, and an absence of infection. When any of these factors is compromised, healing stalls.

Poor circulation is the most common culprit. Without sufficient blood flow, wounds don’t receive the oxygen and nutrients they need to regenerate tissue. This is why people with diabetes, peripheral artery disease, or chronic venous insufficiency are at much higher risk for chronic wounds.

Infection is another major barrier. Bacteria can colonize a wound, forming a biofilm that resists the body’s immune defenses and standard antibiotics. Chronic infection keeps the wound in a constant state of inflammation, preventing healing.

Other contributing factors include: uncontrolled diabetes, malnutrition (especially protein and vitamin deficiencies), smoking, obesity, autoimmune diseases, and medications like corticosteroids that suppress healing.

Warning Signs a Wound Needs Specialist Care

See a wound care specialist promptly if a wound: is not healing after 2-4 weeks despite basic care, is getting larger rather than smaller, has increasing redness, warmth, swelling, or drainage, has a foul odor, shows dark or black tissue around the edges, is accompanied by fever, chills, or increased pain, or is located on the foot or ankle of a diabetic patient.

How Chronic Wounds Are Treated

Effective chronic wound care goes far beyond applying a bandage. At a specialized wound care center like Total Vein & Vascular, treatment may include: debridement (removal of dead or infected tissue to stimulate healing), advanced wound dressings tailored to the wound type and stage, compression therapy for venous ulcers, vascular evaluation and treatment of any underlying circulation problems, infection management including cultures and targeted antibiotic therapy, and offloading devices for foot wounds.

The key insight in modern wound care is that treating the wound alone is not enough — you must also address the underlying cause. A venous ulcer won’t fully heal unless the venous insufficiency driving it is also treated.
