From abscess to fistula: a pattern

What this experience covers

A composite picture of the path many people describe from perianal abscess to anal fistula diagnosis. This draws from multiple anonymized experiences and represents common patterns, not any single person’s story.

Common elements: abscess drainage and initial relief, persistent or returning drainage from the wound, a fistula diagnosis weeks or months later, the emotional weight of learning one condition has become another, and navigating treatment options.

The pattern

The abscess and drainage

Most people describe a perianal abscess as an acute event — sudden, severe pain, swelling, and often a trip to the emergency room. Drainage provides significant relief. Many describe feeling like the problem is behind them. The wound is packed, aftercare instructions are given, and people expect things to heal.

The healing that does not quite finish

Weeks after drainage, some people notice the wound is not closing as expected. Common descriptions:

  • A small amount of drainage that continues from the wound site
  • Intermittent discomfort that comes and goes rather than steadily improving
  • A feeling that something is not right, but difficulty pinpointing what
  • Discharge on underwear or pads that requires ongoing management

The fistula diagnosis

A follow-up appointment or a new visit leads to the diagnosis: an anal fistula — a small tunnel that has formed between the inside of the anal canal and the skin near the anus. Many people describe this moment as deflating. They thought the abscess was a one-time event.

Common reactions:

  • Frustration at having a new, related condition
  • Confusion about what a fistula actually is
  • Worry about whether surgery will be needed
  • Relief at finally having an explanation for the ongoing symptoms

The emotional weight

People frequently describe this transition as harder emotionally than the original abscess. The abscess was acute and dramatic. The fistula is chronic and uncertain. Common feelings:

  • A sense of “here we go again”
  • Difficulty explaining to family or employers why they are still dealing with this
  • Anxiety about treatment options and their impact on daily life
  • Fatigue from months of managing a condition in a sensitive area

Treatment planning

After diagnosis, people describe entering a period of researching options, consulting with colorectal surgeons, and sometimes getting imaging such as an MRI to map the fistula tract. The treatment path depends on the fistula’s complexity, and people commonly describe feeling overwhelmed by the range of options — from fistulotomy to seton placement to newer techniques.

Many describe the waiting period between diagnosis and treatment as one of the hardest parts. The condition is manageable but not resolved, and daily life requires ongoing accommodations.

See all the signs

For this topic, get medical advice if you notice:

  • Severe or worsening pain
  • Heavy bleeding
  • Fever
  • Black stools
  • Fainting or dizziness
  • Pus or unusual discharge
  • Inability to pass stool or gas
  • Unexplained weight loss

Recording how you feel is not the same as being checked. These are the signs that need a doctor’s attention.

Call 911 or go to the emergency room now if you have:

  • bleeding that will not stop, a lot of blood (the toilet water turns red, or you pass large clots), or any bleeding with feeling faint or dizzy
  • fainting, a racing heart or trouble breathing
  • confusion or slurred speech, extreme shivering, no urine in a day, or blotchy skin
  • sudden severe belly pain, or a swollen, hard belly with vomiting or not passing stool or gas
  • you cannot pass urine at all, or your bladder feels full and painful and you can’t empty it
  • redness, swelling or severe pain spreading quickly around your anus, genitals or groin, especially with a fever or feeling very ill
  • a fever with a painful swelling near your anus if you have diabetes or a weakened immune system (for example, from chemotherapy or transplant medicines)
  • black, tarry stools

Call your doctor or go to urgent care today (or the ER if you can’t be seen today) if you have:

  • a temperature of 100.4°F (38°C) or higher, chills, vomiting, or feeling generally unwell
  • pain that is getting worse over days, or severe pain that stops you sitting or sleeping
  • a hot, swollen or very tender lump near your anus or at the top of the crease between your buttocks, or foul-smelling discharge
  • trouble urinating
  • bleeding that is getting heavier or more frequent, or blood mixed into your stool
  • feeling much more tired than usual, looking pale, or getting out of breath more easily than you used to
  • not passing stool for several days, or new belly pain

Make an appointment with your doctor if:

  • you have never had these symptoms checked by a doctor or nurse — whatever your age
  • you have had rectal bleeding for more than 3 weeks
  • your bowel movements have been looser, thinner or more frequent than usual for 3 weeks or more, or you have lost weight without trying
  • symptoms have not settled after a week or so, or keep coming back
  • you notice a new lump near your anus, between your buttocks or in your belly, or an itch or discharge that does not clear
  • you have new leakage or trouble controlling your bowels
  • you are 45 or over, or have a family history of bowel cancer or inflammatory bowel disease, and any of these symptoms are new for you

If you are unsure, it is always reasonable to ask. If things feel overwhelming, call or text 988 (Suicide & Crisis Lifeline) or chat at 988lifeline.org, any time. If you don’t feel safe, call 911.
