Wounds, whether from a minor scrape to a more serious injury, are a common part of life. While most wounds heal without issue, some can become infected, posing serious health risks. Recognizing the signs of an infection early on is crucial to preventing complications.

Here are the key warning signs that a wound may be infected:

1. Increased Redness and Swelling: A certain amount of redness and swelling is normal during the healing process, but if these symptoms worsen over time or spread beyond the immediate area of wound, it may be a sign of infection. Look for redness that extends in streaks from the wound or swelling that continues to increase rather than decrease.
2. Warmth Around the Wound: Infected wounds often feel warmer to the touch than the surrounding skin. This is due to increased blood flow and the body’s inflammatory response to the infection. If the area around the wound feels noticeably warm, it is a potential red flag.
3. Pain That Gets Worse Over Time: Initial pain is expected with any wound, but it should gradually diminish as the wound heals. If the pain persists, worsens, or changes in character (Pain becomes sharp, throbbing, burning), it could indicate an infection. Persistent or escalating pain, especially if it doesn’t improve with over-the-counter pain relief, warrants attention.
4. Discharge or Pus: The presence of pus or cloudy fluid draining from a wound is one of the most obvious signs of infection. Pus is usually yellow, green, or white and may have an unpleasant odor. Any amount of discharge or a change in the color should be taken seriously.
5. Fever and Swollen Lymph Nodes: A fever is a systemic sign that your body is fighting an infection. Even if the wound itself is small, an infection can cause the body to respond with a fever, particularly if the infection is spreading. A persistent low-grade fever or a sudden spike in temperature should be addressed promptly.

   Lymph nodes near the site of a wound may become swollen and tender as they work to filter out bacteria and other pathogens. Swollen lymph nodes in the neck, armpit, or groin (depending on location of wound) can be a sign that the infection in become more severe.

6. Delayed Healing: Most minor wounds should start to show signs of healing within a few days. If your wound is not healing as expected, or it seems to be getting worse, it could be a sign of infection.

   Signs of delayed healing include:

   • the wound remaining open
   • the edges of the wound not coming together
   • new areas of breakdown around the wound

Infections can complicate what might otherwise be a minor injury, turning a small problem into a serious health issue! By being vigilant and recognizing the warning signs of an infected wound, you can take swift action to prevent complications and promote proper healing.
