Diagnosis

Your doctor may be able to diagnose the cause of your itching simply by asking you questions about your symptoms, medical history and personal care habits. If pinworms are suspected, your doctor may suggest doing a test for pinworms. You may also need a physical exam, including a digital rectal exam.

If the cause of your itching isn't obvious or it doesn't respond to initial treatment, your doctor may refer you to a skin specialist (dermatologist). It's possible the cause of the itching may never be identified.
