At a glance
If your fissure healed and then came back — and then healed and came back again — you are experiencing one of the most common and most frustrating patterns in colorectal health.
This guide covers the back-and-forth pattern specifically: what it looks like over months and years, what drives each relapse, how the pattern changes over time, when the cycle signals that the fissure has become chronic, and what realistic long-term management looks like. It complements our broader guide on the fissure healing cycle, which covers the mechanics of healing and relapse in detail. This guide focuses on the longer timeline — the pattern as it plays out across many cycles.
This content draws from forum threads with over 50,000 combined views, including multi-year diary threads where people documented the back-and-forth pattern in real time.
The shape of the pattern
People who live with recurring fissures describe a recognisable shape that repeats:
The acute phase
Something triggers a tear — a hard stool, straining, diarrhoea, or sometimes nothing identifiable. Pain returns. For people who have been through this before, the pain is immediately recognisable. “I know this feeling.” The sharp, burning pain during and after bowel movements. The bleeding. The dread.
For first-time fissures, this phase is frightening. For recurring fissures, it is something worse: demoralising. People describe the sinking feeling of recognition as harder to bear than the pain itself. “Not again.”
The response phase
Self-care measures are resumed or intensified. Fibre, water, sitz baths, stool softeners, dietary changes. For people who have been through the cycle before, this phase is practiced and efficient. They know what to do. They do it.
For some people, this phase also includes returning to prescription topical treatments — GTN, diltiazem, nifedipine — either from a remaining supply or from a new prescription.
The improvement phase
Pain begins to ease. Bowel movements become less dreaded. Bleeding slows or stops. The person begins to feel cautiously optimistic. “I think it is healing again.”
This phase can last days or weeks. For some people, it is steady and predictable. For others, it fluctuates — a good day followed by a setback, then two good days, then another setback. The trajectory is generally upward, but it is not smooth.
The apparently healed phase
Pain is gone or minimal. Bowel movements are manageable. Daily life is no longer dominated by the fissure. For most purposes, the person feels healed.
This is the most psychologically complex phase. People describe wanting to believe it is over while simultaneously bracing for the return. The more cycles they have been through, the harder it is to trust the improvement. “Is this real healing, or am I just in the gap between episodes?”
The trigger
Something happens. Sometimes it is identifiable — a hard stool from dietary change, travel, dehydration, medication side effects, stress. Sometimes it is not. The person did everything right and the fissure came back anyway.
Identifiable triggers that people commonly report:
- Dietary lapses — returning to lower-fibre eating, particularly during holidays, travel, or social occasions
- Dehydration — even a day or two of reduced water intake can change stool consistency
- Medication side effects — iron supplements, codeine-based painkillers, and certain antibiotics are frequently mentioned
- Stress — both the physical effects (increased sphincter tension, disrupted digestion) and the behavioural effects (disrupted routines, poor diet)
- Illness — anything that changes bowel habits, from a stomach bug to a course of antibiotics
- Stopping self-care — the most commonly cited trigger across all accounts
And sometimes: nothing. People describe relapses that occurred during periods of perfect compliance — high fibre, adequate water, consistent sitz baths, soft stools. These “no-fault” relapses are particularly demoralising because they undermine the sense of control that self-care provides.
The return
The familiar pain. The return to the acute phase. The cycle begins again.
How the pattern changes over time
The back-and-forth pattern does not stay static. People who document their experience over months and years describe changes in how the cycle behaves.
Early cycles: acute fissures that heal
In the beginning, the fissure behaves like an acute injury. It tears, it hurts, conservative care helps, it heals. The gaps between episodes may be weeks or months. Each acute episode resolves with consistent self-care. The person may not yet recognise it as a pattern — each episode feels like a one-off.
Middle cycles: the pattern emerges
After two or three relapses, the pattern becomes visible. People describe recognising the cycle for the first time — often with a sinking feeling. The gaps between episodes may shorten. The improvement phase may take longer. The person begins to adjust their entire life around the condition: permanent dietary changes, daily sitz baths, constant attention to stool consistency.
This is also when the emotional toll compounds. Each relapse erodes trust in the body and trust in healing. Anxiety about the next episode becomes a background feature of daily life.
Late cycles: chronicity
After multiple cycles of healing and relapse, the fissure may transition from acute to chronic. Signs of this transition:
- A sentinel pile forms — a small skin tag at the edge of the fissure, indicating the wound has been present long enough for the surrounding tissue to change
- Pain becomes a daily pattern rather than an event-based one — present at some level most days, worsening with bowel movements but never fully resolving
- Conservative care takes longer to produce improvement — what once worked in 2 weeks now takes 6, or does not work at all
- The gaps between “healed” and “relapsed” narrow — until the distinction between the two phases becomes blurred
- Fibrous tissue develops at the wound edges, preventing normal healing
A chronic fissure is not a failure of effort. It represents a change in the tissue and muscle dynamics that self-care alone may not be able to reverse. The internal sphincter spasm, reduced blood flow, and scarring that develop over repeated cycles create conditions that need more help than fibre and water can provide.
The role of the internal sphincter
Understanding the sphincter’s role helps explain why fissures get stuck in the back-and-forth pattern.
The internal anal sphincter is an involuntary muscle that surrounds the anal canal. When a fissure is present, this muscle tends to go into spasm — clenching around the wound. This spasm:
- Reduces blood supply to the fissure, slowing healing
- Increases tension on the wound edges, making re-tearing easier
- Causes pain during and after bowel movements, which triggers more spasm
- Persists even after the fissure closes — the muscle may remain tighter than normal for weeks or months
This creates a cycle within the cycle. The fissure causes spasm. The spasm prevents healing. Partial healing occurs during good periods. The still-tense sphincter then helps re-tear the vulnerable healed tissue when any trigger arises.
Prescription topical treatments (GTN, diltiazem, nifedipine) work by relaxing this sphincter. Botox injections temporarily paralyse it. Lateral internal sphincterotomy (LIS) permanently reduces its tension. Each of these interventions addresses the sphincter directly rather than treating only the wound.
When the pattern means you need more help
There is no exact number of relapses that should trigger escalation. But several markers suggest the conversation is worth having:
- Consistent self-care for 6 to 8 weeks without healing
- Three or more cycles of healing and relapse despite maintaining good habits
- A sentinel pile or skin tag at the fissure site
- Increasing time needed for each recovery
- Pain that never fully resolves between episodes
- Impact on quality of life — including mental health, relationships, work, and daily functioning
If any of these apply, discussing your options with a doctor — ideally a colorectal specialist — is a reasonable next step. Options may include:
- Prescription topical treatments if you have not yet tried them
- Botox injection to temporarily relax the sphincter and give the fissure a healing window
- Lateral internal sphincterotomy (LIS) — a procedure to permanently reduce sphincter tension
- Fissurectomy — removal of the chronic wound and surrounding scar tissue
Many people describe wishing they had escalated sooner. The desire to heal conservatively is understandable and admirable, but enduring more cycles than necessary is not a requirement.
Realistic expectations for long-term management
One of the hardest aspects of the back-and-forth pattern is uncertainty about the future. People ask: will this always be my life?
The honest answer, drawn from many accounts:
For most people, the pattern does end. It ends either through eventual sustained healing with conservative care, or through medical or surgical intervention that breaks the cycle. Permanent, lifelong cycling is not the typical outcome.
But long-term management is usually needed. People who describe lasting recovery almost always describe permanent changes to their habits:
- Fibre as a lifelong commitment, not a temporary treatment
- Hydration as a daily practice
- Attention to stool consistency as an ongoing habit
- Sitz baths during vulnerable periods
- Stress management as a health practice, not an optional extra
These are not punishments. They are the maintenance that keeps the area healthy. People who frame them as “things I do now” rather than “things I have to do because I am broken” describe a healthier relationship with the condition.
Setbacks may still happen. Even with good habits, occasional episodes of harder stools or increased stress may cause minor symptoms. The difference is in how the body responds: well-maintained tissue, with a relaxed sphincter and good blood flow, is more resilient than tissue that has been neglected. A small setback does not have to become a full relapse.
The emotional dimension
The back-and-forth pattern is, by many accounts, as much an emotional experience as a physical one.
People describe:
- Eroded hope. Each improvement comes with the shadow of “but for how long?” Trust in healing diminishes with each cycle.
- Self-blame. “I should not have eaten that.” “I should have kept up with the sitz baths.” People blame themselves for relapses even when the triggers were largely outside their control.
- Isolation. The condition is private. The pattern is invisible to others. The frustration of cycling through pain while appearing fine to the world is exhausting.
- Decision fatigue. Every meal, every glass of water, every bathroom visit carries weight. The cognitive load of managing a condition that might relapse at any moment is significant.
- Grief. Not always named, but present. Grief for the body that used to work without thought. Grief for the spontaneity that chronic management takes away. Grief for the simplicity of not having to think about this every day.
These feelings are valid. If the emotional weight of the pattern is affecting your daily life, it is worth seeking support — from a therapist, from a trusted person, or from a space where you can process what you are going through without judgement.
Talking to your doctor
If you have been through the back-and-forth pattern, your doctor needs to understand the full picture. Helpful information to bring:
- How many cycles of healing and relapse you have experienced
- The approximate timeline — months, years
- What self-care measures you have been following and how consistently
- Whether each episode feels the same or if symptoms are changing
- Any identifiable triggers for each relapse
- What treatments you have tried, including prescriptions
- The impact on your daily life, including mood and mental health
- Whether you have noticed a sentinel pile or skin tag
Your doctor can assess whether the fissure has become chronic and discuss escalation options. You do not need to have reached a crisis to start this conversation. “I have been dealing with this cycle for X months and I would like to discuss next steps” is a perfectly valid reason for an appointment.
When to contact your doctor
Contact your doctor if you experience:
- Heavy bleeding that does not stop with gentle pressure
- Pain that is significantly worse than previous episodes
- Signs of infection — fever, increasing redness, swelling, or discharge
- Unexplained weight loss
- Any new symptoms that were not present in previous flare-ups
- A relapse pattern that is worsening despite consistent self-care
- Emotional distress related to the condition — this is a valid reason to seek support
