Question
For over a year, the navel has been exuding fluid and emitting a foul odor. Each time the navel is touched, it feels like there is something foreign inside. The odor is difficult to eliminate, even after washing, it soon returns to its original state. Why does the navel produce such an odor under these conditions?
Answer
Based on the description, this symptom may be related to acute navicular inflammation in adults. Acute navicular inflammation refers to acute cellulitis of the navicular area, which if the infection worsens, may lead to subcutaneous abscesses, or even develop into periappendicular abscesses, with the risk of secondary peritonitis and sepsis. Common pathogens include Staphylococcus aureus, among others. Treatment involves removing any crusts in the area, using 3% hydrogen peroxide solution and 75% ethanol for cleaning; adults can use hot salt water for soaking; and keeping the navel dry to promote recovery.
