A wound infection
occurs when bacteria enters a break in the skin. The infection may involve just the skin, or affect deeper tissues or organs close to the wound.
Signs and symptoms of a wound infection:
Your symptoms may start a few days after you get the wound, or may not occur for a month or two after the wound happens:
- Warm, red, painful, or swollen skin near the wound
- Blood or pus coming from the wound
- A foul odor coming from the wound
Seek care immediately if:
- You feel short of breath.
- Your heart is beating faster than usual.
- You feel confused.
- Blood soaks through your bandages.
- Your wound comes apart or feels like it is ripping.
- You have severe pain.
- You see red streaks coming from the infected area.
Contact your healthcare provider if:
- You have a fever or chills.
- You have more pain, redness, or swelling near your wound.
- Your symptoms do not improve.
- The skin around your wound feels numb.
- You have questions or concerns about your condition or care.
Treatment for a wound infection
will depend on how severe the wound is, its location, and whether other areas are affected. It may also depend on your health and the length of time you have had the wound. Ask your healthcare provider about these and other treatments you may need:
- Medicine will be given to treat the infection and decrease pain and swelling.
- Wound care may be done to clean your wound and help it heal. A wound vacuum may also be placed over your wound to help it heal.
- Hyperbaric oxygen therapy (HBO) may be used to get more oxygen to your tissues to help them heal. The pressurized oxygen is given as you sit in a pressure chamber.
- Surgery may be needed to clean the wound or remove infected or dead tissue. Surgery may also be needed to remove a foreign object.
Care for your wound as directed:
Keep your wound clean and dry. You may need to cover your wound when you bathe so it does not get wet. Clean your wound as directed with soap and water or wound cleaner. Put on new, clean bandages as directed. Change your bandages when they get wet or dirty.
Help your wound heal:
- Eat a variety of healthy foods. Examples include fruits, vegetables, whole-grain breads, low-fat dairy products, beans, lean meats, and fish. Healthy foods may help you heal faster. You may also need to take vitamins and minerals. Ask if you need to be on a special diet.
- Manage other health conditions. Follow your healthcare provider's directions to manage health conditions that can cause slow wound healing. Examples include high blood pressure and diabetes.
- Do not smoke. Nicotine and other chemicals in cigarettes and cigars can cause slow wound healing. Ask your healthcare provider for information if you currently smoke and need help to quit. E-cigarettes or smokeless tobacco still contain nicotine. Talk to your healthcare provider before you use these products.
