How to Identify an Infected Wound

Cuts and scrapes are unavoidable in daily life. Generally, they tend to heal on their own. However, there are times when bacteria may enter the wound, leading to infection. Recognizing signs of infection early can aid in a faster and more effective treatment process. Most infections can be treated with antibiotics, depending on the severity of the inflammation you're facing. Key symptoms of infection include redness, pus, and constant pain. Learning to identify an infected wound is an essential part of maintaining health.

First, wash your hands thoroughly. Always remember to wash your hands properly before checking the wound. If you're concerned the wound might be infected, touching it with unclean hands could worsen the situation. Make sure to wash your hands thoroughly with antibacterial soap and water before doing anything to your wound.

• Remember to wash your hands after touching the wound.

Carefully examine the wound. You need to remove the bandage from the wound. Be careful not to worsen the situation in this sensitive area. If the bandage is stuck to the wound, you can use water to remove it. The sink faucet will be quite useful in this case.

• Once you have removed the soiled bandage from the wound, discard it properly in the trash. Never reuse a contaminated bandage.

Check for signs of swelling or redness around the wound. When you examine the wound, consider whether it appears red or just slightly more irritated than usual. If the wound is noticeably red and the redness seems to be spreading to the surrounding area, this is a sign of infection.

• The skin around the wound may also feel warmer than usual. If you notice these symptoms, see a doctor.

Assess whether the pain is worsening. The appearance of new pain or a gradual increase in pain intensity is a symptom that the wound may be infected. Experiencing pain or discomfort along with other symptoms (such as redness, heat, and pus) could be an indication of infection. If the pain seems to be getting worse, it's time to seek medical attention. The pain may feel as if it's deep inside the wound. Generally, swelling, warmth, and tenderness in the injured area are initial signs that the wound could be infected.

• You may also experience sharp pain. While itching is not typically a sign of infection, avoid scratching the wound too much. Fingernails can carry bacteria, and scratching can worsen the condition.

Do not apply antibiotic ointment unless advised by a doctor. There is no specific research to prove that topical antibiotic ointments are particularly effective for treating infected wounds. An infection spreading means it has likely entered your body, so applying topical treatments after this stage won't be sufficient to eliminate the bacteria within your body.

• A doctor may prescribe topical antibiotics if the infection is mild and confined to the skin's surface.

Check if the wound is secreting yellow or green pus or fluid. It may also have an unpleasant odor. If you notice yellow or green pus coming from the wound along with cloudy discharge, this is a clear sign that your wound is infected. You should seek medical attention as soon as possible.

• In some cases, fluid discharge may simply be a normal reaction, as long as the fluid is thin and clear. Bacteria can produce clear discharge, rather than yellow or green. In this case, a doctor will examine the wound to identify the specific cause of the infection.

Observe for pus accumulation around the wound. If you notice pus forming beneath the skin, around the wounded area, this may indicate an infection. Even if you see the wound oozing pus, or if you feel a painful swelling under the skin, but no pus is actually draining from the wound, this still could be a sign of infection and should be monitored closely.

After completing the wound inspection, replace the old bandage with a new sterile one. If there are no signs of infection, the bandage will help shield and protect the wound. If you notice signs of infection, a sterile bandage will help prevent further contamination until you can see a doctor.

• The non-adhesive side of the bandage should be placed directly over the wound. The bandage should be large enough to cover the entire wound comfortably.

If the wound continues to discharge pus, see a doctor. Fluid discharge may just be a normal reaction as the body fights infection. However, if the pus is yellow or green and increasing in quantity (or showing no signs of improvement), you should see a doctor. This is especially important if you are also experiencing several other symptoms of infection as mentioned earlier.

Look for any red streaks or swelling around the area of the wound. You may notice red streaks extending from the wound. This could indicate that the infection has spread to the lymphatic system, which is responsible for removing fluid from tissues.

• This infection (called lymphadenitis) can be quite dangerous, and you should seek medical care promptly if you notice red streaks radiating from the wound, especially if you also have a fever.

Locate the lymph nodes (glands) nearest to the wound. The lymph nodes closest to the arm are around the area just below the armpit; for the leg, they are located in the groin area. For other parts of the body, the closest lymph nodes are on either side of the neck, just beneath the jawline on both the left and right sides.

• Bacteria become trapped in these glands as the body goes through the immune process. Sometimes, you may develop lymphadenitis without noticing red streaks on the skin.

Examine the lymph nodes for abnormalities. Use two or three fingers to gently apply pressure and palpate for any swollen lymph nodes, which may also be painful. The easiest way to check is to use both hands to palpate both sides of the lymph nodes simultaneously. Both sides should feel similar and be symmetrical for signs of good health.

Feel for any swelling or pain in the lymph nodes. If you can feel swelling or tenderness, this could be a sign that the infection is spreading, even if you don't see any red streaks on your skin. Lymph nodes are normally about 1 cm in size, so you may not feel them unless they are swollen. When they are enlarged, they may become two or three times their normal size, and you will be able to clearly feel them.

• Swollen, soft, and movable lymph nodes are usually a sign of infection.
• Lymph nodes that are hard, immovable, painful, or persist for more than 1 to 2 weeks should be examined by a doctor.

Measure your body temperature. In addition to symptoms at the wound site, you may also experience a fever. A temperature above 38 ºC could indicate that the wound is infected. You should visit the hospital if you have a fever along with one or more other signs of infection as listed earlier in this article.

Check if you often feel unwell. Another sign of infection can be similar to the feeling of being unwell or sick. If you were injured and have recently started feeling ill, there could be a correlation between the two. Reexamine the wound to check for infection signs, and if you continue feeling unwell, consult a doctor.

• If you experience body aches, headaches, dizziness, nausea, or vomiting, you may have an infection. A new rash would also be a clear indication that you need to see a doctor.

Pay attention to signs of dehydration in your body. Dehydration can also be a sign of an infected wound. Major symptoms of dehydration include infrequent urination, dry mouth, sunken eyes, and dark-colored urine. If you're experiencing these symptoms, be more mindful of your wound, thoroughly checking for additional infection signs and seeking medical attention.

• As your body fights off bacteria, it's essential to drink plenty of water to stay hydrated.

Be aware of types of wounds that are more prone to infection. While most wounds heal on their own, those that are not properly cleaned and treated are more susceptible to infection. Cuts on the hands, feet, and other areas frequently exposed to bacteria are especially vulnerable. Animal and human bites or scratches can also easily become infected.

• Pay particular attention to bites, puncture wounds, and crush injuries. Be cautious with wounds caused by unsanitary objects like sharp knives, rusty nails, or dirty tools.
• If bitten by a dog, consult a doctor about the risk of rabies or tetanus. You may need antibiotics or a tetanus shot.
• If you're healthy and your immune system is strong, most wounds will heal on their own with a low risk of infection. Your immune system is typically well-equipped to prevent infection from taking hold.

Understand the risk factors for infection. If your immune system is compromised due to conditions such as diabetes, HIV, or malnutrition, the likelihood of infection increases. Bacteria, viruses, and fungi, which typically wouldn't cause problems for a healthy immune system, can invade and rapidly multiply in the body. This is particularly true for second- and third-degree burns, where the skin—the body's first line of defense—has been severely damaged.

Recognize severe signs of infection. You may experience a fever or dizziness, and your heart rate may increase. The wound may become hot, swollen, red, painful, and have a foul odor, resembling something decaying or rotting. These symptoms can range from mild to severe, but if you experience a combination of several symptoms, you need medical attention.

• Do not drive if you're feeling dizzy and feverish. If possible, ask a friend or family member to take you to the hospital. You may require strong antibiotics to stabilize your condition.
• When in doubt, get checked. You can't fully diagnose an infection based on information from the internet. A medical diagnosis is the best way to be sure.

Seek medical attention. If you believe your wound is infected, visit the hospital or contact an emergency doctor. This is especially critical if you have other underlying health conditions or infection risk factors.

Consider using antibiotics and NSAIDs (non-steroidal anti-inflammatory drugs). Antibiotics can help combat or prevent bacterial infections, and they may be the most effective way to eliminate infection. NSAIDs can aid in recovery by reducing swelling, pain, and fever. Over-the-counter NSAIDs are available, but the most effective antibiotics usually require a prescription.

• Avoid NSAIDs if you're taking blood thinners. Be aware that these medications can cause stomach ulcers or kidney issues in some individuals. Consult your doctor!

• Ensure proper lighting. It's much easier to spot infection signs in a well-lit room.
• If you don't see signs of healing, like scabbing, the wound may be infected. Seek medical advice if the wound doesn't improve.
• If the wound continues to drain pus, make sure to clean it immediately when you notice, and if the issue persists, consult a doctor.

• Infection can lead to more serious health complications, so if you're unsure about the infection status of your wound, you should see a doctor or healthcare professional.
