At a glance
Many people experiencing anal symptoms want to understand what is going on before seeing a doctor. A gentle external look at home can provide some context, but it has important limits. This guide covers what people commonly describe seeing, the safe approach to self-examination, and why a clinician assessment remains important.
The key message: what you can see externally is only part of the picture. The internal anal canal is not visible without specialist equipment, and many conditions look similar from the outside.
What you might see
Using a hand mirror in a private, well-lit space, some people describe being able to see:
- A small tear or crack in the skin at the anal margin — this is what a fissure looks like when it extends to the external area
- Redness or rawness around the tear
- A small skin tag (sentinel pile) near the fissure — more common with chronic fissures
- Swelling around the area
- Nothing visible at all — many fissures are inside the anal canal and cannot be seen externally
It is important to understand that other conditions — hemorrhoids, skin tags, abscesses — can look similar externally. What you see at home cannot reliably tell you what the condition is.
A safe approach
If you do choose to examine the area at home:
- Wash your hands thoroughly
- Use a hand mirror in a well-lit, private space
- Look gently — do not spread the area forcefully
- Do not insert anything into the anal canal
- Stop if it causes pain — there is no benefit to pushing through discomfort
- Note what you see to discuss with your doctor if helpful
What to avoid
- Do not use a phone torch positioned dangerously close to sensitive skin
- Do not attempt to touch or probe the fissure itself
- Do not try to stretch the area to see deeper inside
- Do not diagnose yourself based on what you see — visual appearance alone is not enough
Why symptoms matter more than appearance
The most useful information for your doctor is not what the fissure looks like, but what you are experiencing:
- When does the pain happen? During or after bowel movements? Both?
- How long does the pain last? Minutes? Hours?
- Is there bleeding? On the paper? In the bowl? How much?
- How long has this been going on?
- What makes it better or worse?
These details are more diagnostically useful than a visual description, and they help your clinician determine the right approach.
When a professional examination is important
A clinician examination can identify things that are impossible to see at home:
- The depth and extent of the fissure
- Whether the fissure is acute or chronic — this affects treatment approach
- The location — typical fissures are at the posterior midline; fissures in unusual locations may need further investigation
- Other conditions that may coexist or mimic a fissure
- Internal anal canal assessment that requires specialised instruments
Most fissure examinations are brief and can often be done by visual inspection alone, without instruments. If an internal examination is needed, your clinician will explain what to expect.
A note on anxiety
It is completely normal to feel anxious about both self-examination and seeing a doctor about this. Many people describe putting off appointments for weeks or months because of embarrassment or fear. Clinicians who work in this area see these conditions routinely. For them, it is straightforward clinical work. For you, it is personal — and that gap is normal.
