Wounds are a normal part of life. Most cuts, scrapes, and injuries heal on their own within a few days or weeks. But sometimes, a wound does not improve even after proper care. When a wound stays open, painful, or infected for a long time, it is known as a chronic wound.
Chronic wounds can seriously affect your health, mobility, and quality of life. They may lead to infection or major complications if ignored.
At Renew Wound in Los Angeles, CA, we specialize in treating slow-healing and complex wounds to help people recover faster and live comfortably again.
A chronic wound is a wound that does not heal within 4 to 6 weeks. Instead of getting smaller and closing, it remains stuck in one stage of healing.
A healthy healing process has three phases. But in chronic wounds, something blocks the healing steps. Blood flow, pressure, infection, and other conditions can slow healing and cause the wound to remain open.
Many chronic wounds are painful, produce drainage, or form dead tissue. Without proper treatment, they may worsen or lead to infection in the bone or bloodstream.
There are many reasons a wound may stop healing:
When blood cannot reach the wound, the tissues do not get enough oxygen and nutrients to repair.
Venous disease → venous leg ulcers
Arterial disease → arterial ulcers
High blood sugar slows healing and can damage nerves and blood vessels, causing diabetic foot ulcers.
People who sit or stay in bed for long periods can develop pressure ulcers (bedsores).
Bacteria or fungi can delay healing if the wound becomes infected.
Some injuries or post-surgery wounds fail to heal as expected.
Smoking
Obesity
Poor nutrition
Aging
Weak immune system
Here are the most common types seen in wound care clinics:
| Type of Chronic Wound | Where It Forms | Key Signs |
|---|---|---|
| Diabetic Ulcers | Feet or toes | Numbness, slow healing, dark or open sore |
| Venous Ulcers | Lower legs | Swelling, varicose veins, heavy drainage |
| Arterial Ulcers | Toes, heels | Severe pain, cool skin, dark tissue |
| Pressure Ulcers | Hips, back, heels | Caused by staying in one position too long |
| Non-healing Surgical Wounds | Surgical incision sites | Open edges, redness, drainage |
| Traumatic Wounds | Any body part | Injury that refuses to heal over time |
Each type has a different cause and requires the right treatment approach.
Normal wounds pass through three healing stages:
1️⃣ Inflammatory Phase
The body cleans the wound, causing redness and swelling.
2️⃣ Proliferation Phase
New tissue and blood vessels grow to close the wound.
3️⃣ Remodeling Phase
The skin becomes stronger and smoother over time.
If a wound remains stuck in stage 1 and does not move forward after 4 to 6 weeks, it is considered chronic.
Seek medical care if you notice:
Pain gets worse instead of better
Bad smell coming from the wound
Increase in drainage (yellow/green pus)
Skin around the wound becomes red or warm
Black tissue (dry dead skin) or yellow slough
Swelling or thick callus around the wound
No improvement after weeks of care at home
Ignoring these signs can lead to infection, hospitalization, or amputation in serious cases.
At Renew Wound, our specialists perform a detailed evaluation:
Proper diagnosis helps us build the right treatment plan so the wound can finally move forward in the healing phases.
Chronic wounds need professional care to heal properly. Common treatment methods include:

Custom footwear or cushions to reduce pressure on foot wounds.
