Infection can develop after an injury or wound to the skin
or mucous membranes (such as the inside of the nose or mouth), a bite or sting,
a tattoo or piercing, or other skin problems. Symptoms of infection may
Increased pain, swelling, redness, or warmth
around the affected area.
Red streaks extending from the affected
Drainage of pus from the area.
Infection in a cut or other skin wound can occur from your
own skin bacteria, from bacteria in the environment, or from bacteria on the
puncturing object. Objects in the wound increase the chances of infection.
Certain areas of the body normally have more skin bacteria, such as the genital
and anal area, skin folds, and the web spaces between the toes. Wounds in these
areas have an increased risk of infection.
Cuts and other skin
wounds may become infected deep inside the wound. When a wound becomes
infected, there may be few noticeable signs at the puncture site. The pain and
swelling may feel as if they are deep inside the wound.
the skin over a puncture wound heals while an infection develops deep within
the puncture wound. When this happens, a pocket of pus (abscess) may form deep within the wound.
If you clean and care for your skin wound, you will reduce your chances
of developing a skin infection.
