In short
Anal fissures are small cracks or tears in the lining of the anus, which is the opening at the end of the large intestine where stool leaves the body. An anorectal fistula is an abnormal tunnel that runs from the anus or rectum to the skin surface. Common symptoms of anal disorders can include bleeding, discharge, itching, pain, and swelling. To make a diagnosis, a health care provider may check the skin around the anus, perform a digital rectal exam, or order tests such as an anoscopy.

How are anal disorders diagnosed?
To make a diagnosis, your health care provider will ask about your symptoms and medical history. Depending upon your symptoms, your provider may:
- Check the skin around your anus for anything that looks abnormal.
- Perform a digital rectal exam (DRE). For this exam, your provider inserts a lubricated, gloved finger into the lower part of your rectum to feel for lumps or anything unusual.
- Order tests, such as an anoscopy.
You may be embarrassed to talk about your anal troubles. But it's important to let your provider know about your symptoms, especially if you have pain or bleeding. The more details you can give about your problem, the better your provider can help you.
How are anal disorders treated?
Treatments vary, depending on the condition you have.

About this page. This page brings together public information from official sources, each cited where it is used. It is not medical advice, it is not a diagnosis, and it does not tell you which treatment to take.
Treatments. Indications are quoted unchanged from official product information (European Medicines Agency, U.S. Food and Drug Administration). They describe what a medicine is approved for, not whether it is right for you. Approved uses can differ between countries. Always read the package leaflet and follow your doctor's or pharmacist's advice.
What people report. Figures marked "reported by Anpheros users" are anonymous counts from at least 20 people who agreed to share them. They show what people report, not what works, and they are not clinical evidence.
Links between terms. "May be associated with" means the link appears in a cited source. It does not mean you have that condition.
In an emergency, call 112 (or your local emergency number). Do not delay seeking medical help because of something you read here.
