Living with PFAPA syndrome

A childhood condition with repeating high fevers every few weeks, mouth sores, sore throat, and swollen neck glands.

Understanding PFAPA syndrome

PFAPA syndrome is a childhood condition with high fevers that repeat on a regular schedule.

Fevers last three to six days and come back every 21 to 28 days. The name stands for periodic fever, aphthous stomatitis (mouth sores), pharyngitis (sore throat), and adenitis (swollen neck lymph nodes). GARD says it happens by chance and is not inherited. It begins in infancy or childhood.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Repeated high fevers
  • Mouth sores (canker sores)
  • Sore throat
  • Swollen neck lymph nodes
  • Tiredness and irritability
  • Headache, joint pain, or muscle aches

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include autoimmune and inflammatory disease specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
