How to Heal an Anal Fissure: Treatment and Recovery
Treatment, recovery and prevention
Anal fissure relief, healing, and recurrence prevention
An anal fissure may be small, but the pain can be difficult to describe to anyone who has not experienced it. A bowel movement can feel sharp, tearing, or like passing broken glass. The pain may then burn or throb for hours—leaving you anxious about the next trip to the bathroom.
That fear can make matters worse. Delaying a bowel movement may cause stool to become harder, while straining or passing another dry stool can reopen tissue that had started to heal.
The short answer: Healing an anal fissure usually requires three things working together: keeping bowel movements consistently soft, reducing anal-sphincter spasm so blood can reach the injured tissue, and relieving and protecting the irritated area while the tear closes. Many recent fissures heal with conservative care. Chronic or repeatedly reopening fissures may need prescription medication, Botox, or surgery.[1][2]
What is an anal fissure?
An anal fissure is a linear tear in the thin tissue lining the anal canal. It most often develops after physical trauma or irritation from a hard bowel movement, constipation, repeated straining, or frequent diarrhea.[1]
Doctors generally describe a fissure as acute when symptoms have been present for fewer than six weeks. A chronic fissure has lasted longer or developed changes such as a small external skin tag, thickened tissue inside the canal, or exposed internal-sphincter fibers.[1]
Sharp bowel-movement pain
People often describe cutting, tearing, or “passing glass” pain while stool passes.
Burning that lingers
Throbbing, burning, or muscle spasm may continue for minutes or hours afterward.
Bright-red blood
A small amount may appear on toilet paper or along the outside of the stool.
Irritation or a skin tag
The area may feel tender or itchy. A chronic fissure can develop a small external tag.
Why do anal fissures develop?
Constipation and hard stools
A large, dry stool can stretch and tear the anal lining. If constipation continues, each bowel movement can injure the same area again. This is why the bowel-softening strategies discussed in our constipation guide are also central to fissure recovery.
Diarrhea and frequent wiping
Frequent loose stool, moisture, digestive residue, and repeated wiping can irritate the anal canal and prevent fragile tissue from recovering.
Pregnancy and postpartum changes
Slower digestion, iron supplements, dehydration, pelvic pressure, labor, and postpartum pain medicine can converge. Read our pregnancy and postpartum relief guide.[5]
Other medical causes
Inflammatory bowel disease, infection, anal trauma, or another medical condition may contribute. Multiple fissures or one away from the usual midline deserves medical evaluation.
Why can such a small tear be so difficult to heal?
A chronic fissure is not simply an ordinary cut in an inconvenient location. Pain can cause the internal anal sphincter to tighten involuntarily. That spasm increases pressure and reduces local blood flow. The next bowel movement stretches the injured area again, causing more pain and more spasm.[1]
Effective treatment attempts to interrupt this cycle from more than one direction: softer stool reduces reinjury, sphincter-relaxing treatment improves blood flow, and local symptom control protects the irritated area while it recovers.
Common anal fissure treatments—and their drawbacks
Most doctors begin with conservative measures, then add prescription treatment when the fissure persists. Each step has potential benefits, but it may also bring side effects, expense, inconvenience, or a disappointing healing rate.
Clinical guidance recommends approximately 25–35 grams of fiber per day, adequate water, and stool-softening measures when necessary.[2]
Soaking in warm water for approximately 10–20 minutes—particularly after a bowel movement—may relax the area and reduce discomfort. In a randomized trial summarized in current clinical guidelines, sitz baths plus fiber relieved pain more effectively than topical anesthetic or hydrocortisone alone.[1]
People frequently try lidocaine, petroleum-based barriers, hydrocortisone, witch-hazel pads, suppositories, and standard hemorrhoid creams. Some temporarily soothe pain or protect irritated skin, but ordinary hemorrhoid products do not necessarily address a fissure’s sphincter spasm.
Topical nitroglycerin relaxes the internal sphincter and improves blood flow. Current colorectal guidelines estimate that it heals approximately half of chronic fissures.[1]
Topical calcium-channel blockers appear to provide healing rates similar to nitroglycerin with fewer headaches, so many clinicians prefer them.[1]
Botulinum toxin temporarily relaxes the sphincter and may be considered when topical medication fails or causes unacceptable side effects. Published patient guidance reports healing in approximately 50–80% of patients.[2]

Surgery for an anal fissure: success, recovery, cost, and risk
When a chronic fissure does not heal with conservative care or medication, a colorectal surgeon may recommend lateral internal sphincterotomy, commonly called LIS. The surgeon divides a carefully measured portion of the internal anal sphincter to lower pressure, improve blood flow, and allow the tear to heal.
How successful is fissure surgery?
Current colorectal guidelines report healing rates of approximately 88–100%, while published patient guidance summarizes success as greater than 90%. That makes LIS the most consistently effective treatment for appropriately selected chronic fissures.[1][2]
What is the recovery time?
LIS is generally an outpatient procedure. The operation often takes less than 30 minutes. Soreness commonly lasts two or three days, and many patients return to routine activities within several days and normal activity within one or two weeks. Complete healing may take approximately six weeks.[3]
What are the disadvantages?
Surgery may involve substantial surgeon, facility, and anesthesia charges; insurance approvals or coverage limitations; time away from work or caregiving; postoperative pain, bleeding, or drainage; and a risk of altered gas or stool control. Across the studies reviewed in current guidelines, reported fecal-incontinence rates ranged from 8–30%, although those figures span different techniques, definitions, follow-up periods, and patient populations.
Modern tailored sphincterotomy, which limits the division to the fissure’s length, may reduce that risk while preserving high healing rates. Surgery requires particular caution in people with pre-existing continence problems, prior anorectal operations, inflammatory bowel disease, known sphincter injury, or a prior obstetric injury.[1]
How long does an anal fissure take to heal?
Pain and bleeding may improve before the tear has fully closed. This can create a false sense that treatment is no longer necessary. Complete healing commonly takes approximately six to ten weeks, even when discomfort improves sooner, and a chronic fissure may take several months to resolve. Fissures present for many months are generally harder to heal than recent ones.[1][2]
- First several days: Burning, irritation, and post-bowel-movement discomfort may begin to lessen.
- Following weeks: Fewer spasms and less bleeding may occur as the tissue begins to close.
- Six to ten weeks: Complete healing may occur when reinjury and muscle spasm remain controlled.
- After healing: Continued stool management is important because the tissue can reopen.
Why do anal fissures keep coming back?
A fissure can recur because the original trigger returns: another hard stool, constipation, straining, frequent diarrhea, continued sphincter tightness, or repeated local irritation. Even a surgically treated fissure can recur after another episode of hard stool or trauma, although recurrence is less common after successful LIS than after nonsurgical treatment.
Stopping prevention as soon as the pain disappears is a common mistake. In a controlled study, continued fiber after healing reduced recurrence from 60% to 16%. The most effective maintenance plan is often simple but unglamorous: maintain a soft, formed stool, avoid straining, respond early to constipation or diarrhea, and protect the area when irritation begins.[1]
Fast fissure relief—and support through the healing process
Healing a fissure is difficult with any treatment. Fiber, prescription ointment, Botox, and even surgery cannot make injured tissue rebuild itself overnight. The pain may improve first, but the tear can remain fragile for weeks or months—and one difficult bowel movement can open it again.
A fissure therefore needs fast symptom relief on the front end and continued protection throughout recovery. This is where Pranicura can make an immediate and lasting difference.
Pranicura’s patented, steroid-free formula combines four active ingredients designed to relieve itching, burning, irritation, and discomfort while protecting sensitive perianal tissue and managing moisture.[6]
Helps protect irritated tissue and reduce exposure to further irritation.
Provides skin-protectant and anti-itch benefits for moist anorectal conditions.
Helps soothe itching, burning, and irritation while protecting the area.
Provides a cooling sensation and external analgesic relief.
Relief first. Healing next. Protection after the pain stops.
Pranicura can begin helping before the fissure has had time to close. When burning, itching, pain, and irritation calm down, it becomes easier to stop scratching, over-cleaning, clenching, and repeatedly disturbing the tissue. Its protectant ingredients also help shield the sensitive external area from moisture, residue, and friction.
That protection becomes especially important once the fissure starts to feel better. Feeling less pain does not necessarily mean the tissue is fully healed. Continuing to use Pranicura during the weeks or months that follow can help protect the still-fragile area and reduce the irritation that may contribute to reopening.
Pranicura can also remain part of the routine after the fissure feels healed. Because it is steroid-free, it can be used as directed for longer-term maintenance without the steroid-related skin-thinning concern associated with prolonged hydrocortisone use. Many customers continue applying it after bowel movements, at bedtime, or whenever the first signs of irritation return.[7]
These reviews describe individual experiences, and results vary. However, the pattern repeated across many customer stories is important: Pranicura relieved symptoms quickly, consistent use supported healing over time, and continued use helped customers avoid returning to the same painful cycle.

Consider Pranicura Before Surgery
Anal fissures vary in severity. As explained earlier, many acute fissures and some chronic fissures can heal without an operation, while severe, long-standing, or treatment-resistant fissures may only fully heal after surgery. Anyone advised that surgery is medically necessary should follow the guidance of a colorectal specialist.
An anal fissure can interfere with sleep, driving, working, exercise, travel, intimacy, pregnancy recovery, and caring for a child. It is also notoriously slow to heal. Whether someone uses conservative care, prescription ointment, Botox, or surgery, the tissue still needs time—and often several weeks or months—to become strong again.
Surgery can be highly successful, but it may also involve specialist consultations, insurance restrictions, surgeon and facility charges, anesthesia, recovery time, time away from work, and continence risk. When surgery is not urgently necessary, it is reasonable to ask whether a complete nonsurgical plan—including soft stools, prescribed therapy when appropriate, and consistent use of Pranicura—should be tried first.
Pranicura can relieve the worst symptoms quickly, protect the area as the fissure gradually heals, and continue supporting the tissue after it feels better so it is less likely to reopen. It supports the full healing period—not only the first few days of pain.
Frequently asked questions
Can an anal fissure heal on its own?
Yes. Many recent fissures heal with soft stools, fiber, adequate water, sitz baths, and protection from reinjury. A persistent or repeatedly reopening fissure may need prescription treatment or a procedure.
How do I know whether my fissure is healing?
Pain should become less intense, post-bowel-movement burning should resolve more quickly, and bleeding should decrease. Symptom improvement does not always mean the tear has completely closed. A clinician can confirm healing when needed.
Why did my fissure reopen after I felt better?
The tissue may not have finished healing, or another hard stool, episode of diarrhea, or bout of straining may have injured the same location. Continue preventive bowel habits after the pain disappears.
Are prescription ointments better than OTC products?
They serve different purposes. Nitroglycerin, diltiazem, and nifedipine are prescribed to relax the sphincter and improve blood flow. OTC anorectal products generally focus on temporary symptom relief or skin protection. A combined plan may be appropriate.
Is surgery the only cure for a chronic fissure?
No. Prescription ointments and Botox can heal some chronic fissures. LIS has the highest established healing rate, but its risks, cost, and recovery burden mean treatment should be individualized.
Can I continue using Pranicura after my fissure feels healed?
Yes. Symptom relief may occur before the tissue is fully repaired. Because Pranicura is steroid-free, it can remain part of a longer-term maintenance routine while the area strengthens and whenever early irritation returns. Continue the bowel-softening habits that helped the fissure heal.
When should I see a doctor?
Seek medical advice for severe or worsening pain, persistent or recurrent bleeding, fever, pus or unusual drainage, black stool, unexplained weight loss, a significant bowel-habit change, multiple or unusually located fissures, or symptoms that do not improve. Pranicura’s label directs users to obtain a medical diagnosis and to stop and seek advice for bleeding, worsening symptoms, a reaction, or no improvement within seven days.
