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.

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) for further evaluation. A rectal exam may be all that's required for you to get an answer — and a solution — to a very uncomfortable problem.

Other tests, such as proctoscopy or colonoscopy to view more of the digestive tract, are sometimes needed to identify an underlying cause of anal itching. However, the precise cause of the itching may never be identified.
