Wound Problems
Signs that a wound is not healing the way it should
Quick Facts
- Type: Skin and tissue (wound) symptom

- Warning signs: Spreading redness, pus, fever, warmth
- Seek urgent care if: Fever, red streaks, rapidly spreading redness
Overview
Wound problems refers to any sign that a wound, whether a cut, scrape, surgical incision, burn, or pressure sore, is not healing the way it should. Healthy wounds typically become less painful day by day, with edges that draw together and a gradual return to normal skin. When healing stalls or goes wrong, the wound may stay open, drain fluid, become more painful, or show signs of infection.
Recognizing wound problems early matters, because a small issue such as a mild infection can become serious if it is not treated. People with diabetes, poor circulation, a weakened immune system, or limited mobility are especially prone to slow-healing and complicated wounds and should monitor them closely.
Common Causes
Several factors can cause a wound to heal poorly or develop complications:
- Infection: Bacteria entering the wound cause redness, warmth, swelling, pain, and pus.
- Poor blood flow: Reduced circulation, as in peripheral artery disease, starves the tissue of oxygen and nutrients needed to heal.
- Diabetes: High blood sugar impairs healing and reduces sensation, so injuries go unnoticed and worsen.
- Pressure: Constant pressure over a bony area causes pressure sores in people who are bedbound or use a wheelchair.
- Excess tension or movement: Pulling on an incision can cause it to reopen (dehiscence).
- Foreign material or dead tissue: Debris or non-living tissue in the wound delays healing.
- Smoking, poor nutrition, and certain medicines: All can slow the body's repair process.
Associated Symptoms
The signs that accompany a wound problem help show how serious it is:
- Increasing redness around the wound, especially if it spreads
- Warmth and swelling of the surrounding skin
- Pain that worsens instead of easing over time
- Cloudy, yellow, green, or foul-smelling drainage (pus)
- A wound that reopens or fails to close
- Red streaks spreading from the wound
- Fever, chills, or feeling generally unwell
Red streaks, fever, or spreading redness suggest the infection may be moving beyond the wound and require prompt medical attention.
Diagnosis & Evaluation
A clinician evaluates a problem wound by examining it and reviewing your overall health, medications, and any conditions such as diabetes or circulation problems.
- Wound inspection: Size, depth, edges, tissue color, and drainage are assessed.
- Wound culture: A swab or tissue sample can identify the bacteria causing an infection and guide antibiotic choice.
- Blood tests: May check for infection, blood sugar control, and nutrition.
- Circulation tests: Such as checking pulses or blood pressure in the limb when poor blood flow is suspected.
- Imaging: If a deeper infection or bone involvement is a concern.
Treatment & Management
Treatment is aimed at the cause and at supporting healing:
- Cleaning and dressing: Keeping the wound clean and appropriately covered protects it and supports healing.
- Antibiotics: Prescribed when infection is present, either as a cream or by mouth depending on severity.
- Debridement: Removing dead or infected tissue so healthy tissue can grow.
- Managing underlying conditions: Controlling blood sugar, improving circulation, and addressing nutrition all speed healing.
- Pressure relief: Repositioning and special mattresses or cushions for pressure sores.
- Specialized care: Chronic or complex wounds may need a wound-care clinic, advanced dressings, or other therapies.
For minor wounds at home, wash gently with clean water, keep them covered, and watch for the warning signs above.
Supporting your overall health speeds healing as well. Eating enough protein, staying hydrated, not smoking, and keeping any chronic conditions such as diabetes under good control all help wounds close. Avoid the temptation to pick at scabs or repeatedly remove dressings, as this disturbs new tissue. If a wound is in an area that moves a lot or rubs against clothing, protecting it with a suitable dressing reduces irritation. Keeping track of whether a wound is gradually getting smaller, rather than larger or unchanged, is one of the simplest ways to tell whether it is on the right track.
When to See a Doctor
Contact a clinician if a wound:
- Is not healing or is getting larger after several days to a couple of weeks
- Becomes more red, swollen, warm, or painful
- Drains pus or has a bad smell
- Reopens or its edges separate
Seek urgent or emergency care if you develop a fever or chills, see red streaks spreading from the wound, notice rapidly spreading redness, or have a deep or large wound that will not stop bleeding. People with diabetes or poor circulation should have foot and leg wounds checked early, as these can deteriorate quickly.
Frequently Asked Questions
How do I know if my wound is infected?
Signs of infection include increasing redness, warmth, swelling, worsening pain, and cloudy, yellow, green, or foul-smelling drainage. Fever or red streaks spreading from the wound suggest a more serious infection that needs prompt care.
Why is my wound not healing?
Common reasons are infection, poor blood flow, diabetes, ongoing pressure, dead tissue in the wound, smoking, and poor nutrition. A wound that has not improved in one to two weeks should be evaluated to find and treat the cause.
How should I care for a wound at home?
Wash your hands, clean the wound gently with clean water, and keep it covered with a clean dressing, changing it as directed. Avoid harsh antiseptics on open tissue, do not pick at scabs, and watch for signs of infection.
When is a wound an emergency?
Seek emergency care for a wound with heavy bleeding that will not stop, rapidly spreading redness, red streaks, high fever, or signs of severe infection. Deep puncture wounds, animal bites, and dirty wounds may also need urgent attention and a tetanus update.
Do I need antibiotics for every wound?
No. Most minor, clean wounds heal with good local care and do not need antibiotics. Antibiotics are used when there is an infection or a high risk of one, and should be prescribed by a clinician rather than taken on your own.
