Fistulotomy recovery: week by week

What this experience covers

A composite picture of what people commonly experience during the weeks of recovery after a fistulotomy — a procedure where the fistula tract is opened and left to heal from the inside out. This draws from multiple anonymized experiences and represents common patterns, not any single person’s story.

Common elements: the surgery itself, first week pain management, wound packing changes, the slow visible filling of the wound, key milestones, and the weeks-long timeline that is longer than most people expect.

The pattern

Surgery day

People describe fistulotomy as a relatively short procedure, often under general anaesthesia. Waking up, the area is numb or packed, and pain is initially managed with medication. Many people go home the same day. The most common surprise: learning that the wound will be left open, not stitched.

Common reactions:

  • Relief that the procedure is done after weeks or months of planning
  • Anxiety about caring for an open wound in a sensitive area
  • Feeling groggy and sore but not in acute pain yet

Week 1: managing the pain

Once the anaesthesia and initial pain medication wear off, the first week is commonly described as the hardest. Pain is most intense in the first 3 to 5 days, especially during and after bowel movements.

What people describe:

  • Pain that is sharp during bowel movements and aching between them
  • Stool softeners and fiber as essential, not optional
  • The first post-surgery bowel movement as a significant anxiety event
  • Dressing changes that are uncomfortable but manageable
  • Limited mobility and time off work for most people

Weeks 2 to 3: wound packing and settling in

By week two, the acute pain has typically reduced. People shift from pain management to wound management. District nurses, practice nurses, or self-care routines handle packing changes.

Common experiences:

  • Wound packing changes that become routine, though not pleasant
  • Gradually increasing activity — short walks, light tasks
  • Ongoing drainage that requires dressings and pads
  • Learning to read the wound’s progress and what healthy healing looks like

Weeks 4 to 6: visible progress

This is when most people describe seeing real change. The wound visibly fills in from the bottom, and the surface area shrinks. Milestones that people commonly note:

  • First comfortable shower without wincing
  • First normal bowel movement without significant pain
  • Sitting comfortably for longer periods
  • Returning to work or regular activities
  • Needing fewer or no dressings

Weeks 6 to 8 and beyond: the final stretch

Healing continues but slows. People describe this phase as requiring patience. The wound may look nearly closed but still needs time to fully mature. Some people heal in 6 weeks; others take 10 to 12.

The emotional arc at this stage is generally positive but tinged with impatience. People are ready to be done, and the last stretch of healing often feels the longest. Follow-up appointments confirm healing progress and provide reassurance.

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.
