Signs and symptoms of familial Mediterranean fever usually begin during childhood. Signs and symptoms occur in bouts called attacks that last one to three days.

Signs and symptoms of familial Mediterranean fever include:

  • Fever
  • Abdominal pain
  • Chest pain
  • Achy, swollen joints
  • Constipation followed by diarrhea
  • A red rash on your legs, especially below your knees
  • Muscle aches
  • A swollen, tender scrotum

Between attacks, you'll likely feel normal. Symptom-free periods may be as short as a week or as long as months.

When to see a doctor

If you or your child experiences sudden worrisome signs or symptoms, such as shortness of breath or passing out, call 911 or emergency medical help.

See your doctor if you or your child has a sudden fever accompanied by pain in the abdomen, chest and joints.
