When to seek medical advice

By Mayo Clinic staff

See your doctor if you develop any of the following signs:

  • A large scaly patch on your back, chest or abdomen
  • A rash across your back, chest or abdomen
  • A rash on your arms, legs or face

Also contact your doctor if you've been diagnosed with pityriasis rosea, and the rash doesn't go away within three months.
