How to tell if a wound is healing or infected – Recognising signs of an infected cut or wound

Human bodies are clever enough to mend bones, fight invasions and regenerate new skin. After an injury your body starts healing itself just minutes later, but this process isn't always straightforward.

Do you have a cut that feels like it's taking a long time to heal? If it's been a month or more, you could have an infected wound. Recognising signs of wound infection is important. Use our guide for how to tell if a wound is healing or infected.

Wounds can appear anywhere on the body. They usually form as a result of trauma (e.g. cuts or lacerations) or as a result of surgery (if a cut is made during an operation).

An infected wound can happen when germs or bacteria find a way into the sensitive tissues beneath our skin via the wound. Infection can develop any time between two to three days after the cut occured, until it's visibly healed.

Luckily, infected cuts can be prevented with proper wound protection using Elastoplast plasters.

Recognising signs of wound infection is important so you know when to see your doctor for the appropriate treatment. All wounds, even smaller ones, can turn into a chronic wound over time, so you should monitor it throughout the healing process.

To tell if a wound is healing or infected, learn about the symptoms of an infected cut below:

Wounds often feel warm at the start of the healing process when the white blood cells are fighting germs. An infected wound may have a continued localised fever after the first five days.

A high body temperature is a sign the infection has entered your bloodstream and is spreading through your body.

It's normal for the area to be red right after the injury took place. This is because red blood cells are being sent there to supply oxygen and other nutrients. However, persistent redness and swelling after five days could indicate an infected wound.

Normally pain will gradually subside if a wound is healing, so long-lasting or increasing pain is a sign of infection. Pain should decrease with medication and not get worse. An achy body is another symptom.

After some initial discharge of pus and blood, the wound should be clear. Infected cuts can ooze excess amounts of a thick, discoloured liquid that emits a horrid odour.

For some infected wounds, excess numbness or pain and impair your usual movement or function of the area.

If you notice any of these symptoms a week after sustaining an injury, speak to your doctor to receive the appropriate treatment.

An infection can spread into the deeper tissues if an infected wound isn't treated promptly. This is called cellulitis, and the infection can spread to other body parts through your blood.

On the whole, an infected cut becomes more painful over time, while an uninfected cut will gradually improve. If you're unsure how to tell if a wound is healing or infected, look out for the following signs your wound is healing:

• Swelling: This occurs when your immune system is repairing the wound, as blood vessels are widened to ease blood flow and send oxygen. This shouldn't last longer than five days.
• Scabs: After a wound bleeds and clots, a scab can form. However, protecting your wound with a plaster enables moist wound healing - preventing scabs from forming and reducing the risk of scarring.
• Tissue growth: As wounds heal, new tissue will form over the wound. This can take a couple of weeks, depending on the severity of the wound.
• Scarring: This is a natural part of the healing process after a skin injury has been sustained. Reduce the appearance of scars using Elastoplast Scar Reducer Patches.
