At a glance
A tearing sensation near the anus is a common reason people search for answers. It can be alarming — the area is sensitive, the symptom is unfamiliar, and it is difficult to see what is happening.
The most common cause is an anal fissure — a small tear in the lining of the anal canal. But tearing can also result from skin conditions, local irritation, infections, or less common conditions. This guide covers the main possibilities, what distinguishes them, and when to seek a professional assessment.
This is not a diagnostic tool. It is a starting point for understanding what might be happening and how to describe it to a doctor.
Anal fissures: the most common cause
A fissure is a small tear in the thin, delicate lining of the anus. It is the most frequent cause of a tearing sensation in this area.
People with fissures commonly describe:
- Sharp, cutting, or tearing pain during a bowel movement
- Pain that continues as a burning or throbbing for minutes to hours afterwards
- Bright red blood on toilet paper (usually a small amount)
- Symptoms that started after a hard or large bowel movement
- A visible split or crack near the anal opening
Fissures are very common and are usually caused by passing hard or large stools, straining, or constipation. Most acute fissures heal with self-care — fibre, hydration, sitz baths, and avoiding straining.

Skin conditions affecting the perianal area
The skin around the anus is thin and sensitive. Several skin conditions can cause it to crack, split, or tear:
- Eczema or dermatitis — itchy, inflamed skin that can become dry and fragile, leading to small cracks or splits. Contact dermatitis from soaps, wipes, or creams is a common trigger in this area.
- Psoriasis — can affect the perianal region, causing dry, thickened patches that are prone to cracking.
- Fungal infections — moisture and warmth can promote fungal growth, leading to irritated, fragile skin.
- Lichen sclerosus — a less common skin condition that can affect the genital and perianal area, causing thin, fragile skin that tears easily.
Skin conditions tend to cause more generalised irritation and itching rather than the sharp, localised pain of a fissure. The tearing may occur in multiple spots rather than a single point.
If a skin condition is suspected, treatment focuses on the underlying cause rather than the tear itself.
Trauma and irritation
Tearing can result from direct trauma or irritation to the area:
- Hard or large stools — the most common mechanical cause
- Vigorous wiping — particularly with dry toilet paper
- Anal intercourse — without adequate preparation or lubrication
- Excessive cleaning — overwashing or using harsh products can strip the skin’s natural barrier
In these cases, the tearing usually heals once the cause is addressed. Gentle cleaning, barrier creams, and avoiding the triggering activity are the standard approach.
Infections
Less commonly, tearing or breakdown of the skin near the anus can be associated with infection:
- Perianal abscess — a pocket of infection that can cause the overlying skin to become swollen, painful, and eventually break down. This typically presents with a visible, tender lump and sometimes fever.
- Sexually transmitted infections — certain infections can cause ulceration or skin breakdown in the anal area. These tend to look different from a typical fissure.
- Herpes simplex — can cause small, painful blisters or ulcers in the perianal region that may be mistaken for fissures.
Infections generally require specific treatment. If you suspect infection — particularly with fever, discharge, or symptoms following sexual contact — see a doctor.
Inflammatory bowel disease
Crohn’s disease, in particular, can cause perianal complications including fissures, fistulas, and skin breakdown. Crohn’s-related fissures tend to:
- Occur in atypical locations (not just the midline)
- Be multiple or recurrent
- Heal more slowly than typical fissures
- Be accompanied by other digestive symptoms
If tearing near the anus is part of a broader pattern of digestive concerns, mention all your symptoms to your doctor so they can consider the full picture.
How to describe your symptoms to a doctor
If you decide to see a doctor, it helps to have clear notes about what you are experiencing. Consider noting:
- When it started — was there a specific event or did it develop gradually?
- What it feels like — sharp, burning, tearing, itching, aching?
- When it happens — during bowel movements, all the time, at specific times?
- Any bleeding — colour, amount, when it occurs?
- What makes it better or worse — certain activities, foods, positions?
- Any other symptoms — discharge, lumps, itching, changes in bowel habits?
- What you have already tried — creams, dietary changes, baths?
Being specific helps your doctor narrow down the possibilities more quickly. You do not need to have answers to all of these — even partial information is useful.
Self-care while waiting for an appointment
If your symptoms are not severe and you are waiting to see a doctor, the following measures are commonly used for general comfort:
- Keep the area clean with warm water — avoid soaps or wipes with fragrance
- Pat dry gently rather than rubbing
- Increase fibre and water intake to soften stools
- Avoid straining during bowel movements
- A warm sitz bath can provide temporary relief
- Wear loose, breathable clothing
These measures are unlikely to cause harm and may help regardless of the underlying cause.
