At a glance
After a perianal abscess is drained, most people feel significant relief relatively quickly. The intense pressure and pain from the trapped infection eases once the pus has a way out.
However, drainage is just the first step. The wound left behind needs time and care to heal properly. This page covers what to expect during recovery, how to care for the wound, what to watch for, and when to seek care.
What happens after drainage
- The wound is intentionally left open so it can heal from the inside out
- You may have packing in the wound initially, which will need to be changed
- There will be some drainage from the wound — this is expected and healthy
- Pain relief is usually dramatic compared to before drainage, though the area will still be sore
- You will typically be given instructions for wound care and follow-up
The first week
The first few days after drainage are about managing comfort and keeping the wound clean. People commonly report:
- Soreness around the wound, though much less than before drainage
- Drainage of fluid from the wound, sometimes blood-tinged
- Fatigue as the body recovers from the infection and procedure
- Relief mixed with anxiety about what comes next
- Packing changes that can be uncomfortable — it is okay to take pain relief beforehand
Most people take a few days to a week off work after drainage, depending on their job and the size of the abscess.
Wound care and packing
- If packing was placed, a nurse or your doctor will change it — often daily at first, then less frequently
- Some wounds are left without packing and covered with a dressing instead
- Keeping the wound clean is essential. Rinse gently after bowel movements.
- Let the wound heal naturally from the bottom up. Do not try to close or cover the opening tightly.
- The wound will gradually get smaller over the weeks as new tissue fills in from below
Sitz baths for wound care
Sitz baths are one of the most commonly recommended parts of recovery after abscess drainage. People find them helpful for:
- Keeping the wound clean without harsh wiping or scrubbing
- Soothing soreness and discomfort around the area
- Softening any crusting around the wound edges
- General comfort and relaxation during a stressful recovery period
Warm water for 10 to 15 minutes, a few times a day and after bowel movements, is the typical approach.
Pain timeline
- Days 1 to 3 — soreness at the wound site, but typically much better than the abscess pain. Pain relief medication helps.
- Days 4 to 7 — gradual improvement for most people. Packing changes may be the most uncomfortable part.
- Weeks 2 to 4 — continued healing. Most people report manageable discomfort rather than significant pain.
- Weeks 4 and beyond — the wound is usually well on its way to closing. Some people heal faster, some slower.
Everyone’s experience is different. Healing is not always a straight line.
Signs of recurrence
Abscesses can come back. People report recurrence as:
- New swelling and pain in or near the same area
- A return of the pressure and tenderness that felt like the original abscess
- Fever alongside new swelling
- Drainage that had stopped but starts again
If you suspect the abscess is returning, do not wait. Seek medical attention promptly.
Fistula risk
Around half of perianal abscesses are reported to lead to a fistula — a persistent tunnel between the anal canal and the skin. Signs that a fistula may have formed include:
- Ongoing drainage from the wound area weeks after the abscess was treated
- A small opening that does not fully close
- Recurring swelling in the same spot
A fistula is not a sign that anything went wrong with your drainage. It is a common progression of the original infection. Your doctor will discuss treatment options if one develops.
What tends to help
- Following wound care instructions carefully — this gives the wound the best chance to heal cleanly.
- Sitz baths — consistently one of the most helpful things people report during recovery.
- Fiber and hydration — soft stools reduce pain during bowel movements while the wound heals.
- Attending all follow-up appointments — monitoring for proper healing, recurrence, and fistula development.
- Resting when your body asks for it — recovery from an infection takes energy.
What tends to make things worse
- Skipping wound care or packing changes
- Constipation and straining during bowel movements
- Ignoring new swelling, fever, or increasing pain
- Returning to strenuous activity before the wound has healed sufficiently
- Not attending follow-up appointments
Talking to your doctor
During recovery, keep track of:
- How the wound looks — is it getting smaller over time?
- The amount and type of drainage
- Your pain levels and whether they are improving
- Any new lumps, swelling, or tenderness nearby
- Whether the wound seems to have stalled in healing
If you experience severe pain, heavy bleeding, fever, or symptoms that concern you, seek medical care.
