Common Symptoms of Anorectal Fistula: Don’t Ignore These Signs
An anorectal fistula is a serious health issue that can cause significant discomfort if not treated. It’s important to recognize the signs early for timely diagnosis and treatment.
In this blog, we will explain what an anorectal fistula is, its common symptoms, and why you should seek medical help if you think you have a fistula. According to Dr. Raviram S, a specialist offering trusted fistula treatment in Thrissur at Thrissur Piles Clinic, early intervention is key to managing this condition effectively.
What is an Anorectal Fistula?
An anorectal fistula — also known as fistula in ano, or Bhagandar in Hindi — is an abnormal tunnel that forms between the inside of the anal canal and the skin outside the anus. It almost always develops after an anal abscess (a pus-filled infection) fails to heal completely.
While anyone can develop a fistula, it is more commonly diagnosed in men, and searches for “fistula symptoms in men” are common because certain risk factors — like anal gland blockages and Crohn’s disease — are seen more frequently in men.
Common Symptoms of Anorectal Fistula:
Recognizing the signs and symptoms of fistula early can help you get treatment and avoid complications. Here are the most common signs to look out for:
- Persistent Pain: Pain is one of the most common symptoms of anal fistula. It can be constant or come and go, and it often gets worse when sitting, during a bowel movement, or with pressure on the anal area. If the tract gets blocked and infected, the pain can turn sharp and throbbing, sometimes worse at night.
- Discharge: A hallmark sign of fistula is discharge from a small opening near the anus. It can be pus-like, blood-tinged, or clear and watery, often with an unpleasant smell. It may stain underwear and irritate the skin. Note: If discharge suddenly stops, it doesn’t mean the fistula has healed — the tract may just be blocked, which can lead to a painful abscess.
- Swelling and Redness: Redness and swelling near the fistula opening are frequent fistula symptoms. The area may feel warmer and more sensitive due to inflammation or pus buildup, and a small lump can sometimes be felt or seen — easily mistaken for a pile until examined properly.
- Recurring Abscesses: Repeated abscesses in the same spot often point to an untreated fistula in ano. An abscess is a pus collection from infection, and it tends to return again and again until the underlying tract is treated — this cycle is a key sign of a chronic fistula.
- Fever and Fatigue: Fever, chills, and tiredness signal that an infection is spreading rather than staying localized and need prompt medical attention rather than home care.
- Difficulty with Bowel Movements: Bowel movements can become painful, leading some people to delay using the bathroom. This can cause constipation, adding more pressure on the fistula and worsening the condition.
- Itching and Skin Irritation: Ongoing leakage can irritate the surrounding skin, causing persistent itching and soreness — an often-overlooked but common symptom.
- A Visible or Palpable Opening: Many patients first notice a small pit or opening near the anus, sometimes with a firm tract felt underneath the skin — often what prompts people to search “signs of a fistula” online.
Why You Shouldn't Ignore These Signs:
Ignoring the symptoms of an anorectal fistula can lead to serious problems, including:
- Chronic Infection: Untreated fistula in ano lets infection persist and spread, damaging surrounding tissue over time.
- Multiple Fistula Tracts: Ignored fistula symptoms can branch into extra tunnels, making treatment more complex.
- Complex Fistula-in-Ano: Connected tracts near the sphincter muscles require more extensive, staged surgery.
- Sphincter Weakness: Long-term infection can weaken sphincter muscles, affecting bowel control.
- Delayed Healing: The longer a fistula is ignored, the lower the success rate of simple, single-stage surgery.
- Recurring Abscess Cycles: Untreated tracts keep causing painful abscesses that return again and again.
- Increased Risk of Complications: Long-neglected, chronic fistulas have rarely been linked to more serious tissue changes.
- Impact on Quality of Life: Chronic fistula pain, discharge, and unpredictable flare-ups affect daily routines and mental well-being.
When to Seek Medical Attention?
If you notice any of the symptoms mentioned above, see a doctor right away. Early diagnosis and treatment can improve your outcome and prevent complications. Dr. Raviram S can perform a thorough examination, possibly including imaging tests, to diagnose the fistula and recommend the best treatment.
Conclusion:
Anorectal fistulas are a serious condition that shouldn’t be ignored, even when symptoms feel mild. Recognizing the signs early and seeking prompt treatment can prevent complications and make recovery much easier.

Frequently Asked Questions:
The key warning signs of anal fistula include persistent throbbing pain near the anus, continuous pus or blood discharge, swelling or a tender lump, skin irritation, recurring abscesses in the same spot, and fever if the infection spreads.
Early signs of fistula are often subtle — mild discomfort while sitting, occasional spotting on underwear, slight itching, or a small tender lump near the anus that comes and goes before it turns into a full-blown abscess.
In most simple fistula cases, the discharge is pus, blood, or clear fluid — not stool. In complex or high fistulas (often linked to Crohn’s disease), occasional stool or mucus leakage can occur, which needs prompt evaluation.
Discharge is usually pus-like and thick, blood-tinged, or clear and watery, often with a foul smell. It can stain underwear and irritate the surrounding skin.
It can be both. Pain often flares when the tract gets blocked (causing a mini-abscess) and eases once it drains, only to return later — this on-and-off cycle is a classic fistula symptom pattern.
Symptoms are largely the same as in women — persistent pain, discharge, swelling, and recurring abscesses — though fistulas are diagnosed more often in men.
