Tests and diagnosis

By Mayo Clinic Staff

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

If the cause of your itching isn't obvious, your doctor may refer you to a skin specialist (dermatologist) or a doctor who specializes in treating rectal and anal problems (proctologist). He or she may do other tests, such as proctoscopy or colonoscopy to view more of the digestive tract. But it's possible the cause of the itching may never be identified.
