If infection is the cause of your swollen lymph nodes and isn't treated, these complications might occur:

  • Abscess formation. An abscess is a localized collection of pus caused by an infection. Pus contains fluid, white blood cells, dead tissue and bacteria or other invaders. An abscess may require drainage and antibiotic treatment. An abscess may cause significant damage if it involves a vital organ.
  • Bloodstream infection (bacteremia). A bacterial infection anywhere in your body can progress to sepsis, caused by an overwhelming infection of the bloodstream. Sepsis may result in organ failure and death. Treatment involves hospitalization and intravenous antibiotics.
