How to Treat Anal Fissures at Home: 6 Tips for Fast Pain Relief

Anal fissures can make each bowel movement a painful experience, with pain sometimes lasting from minutes to hours afterward. According to the American Society of Colon and Rectal Surgeons (ASCRS), anal fissures are quite common and often cause severe pain and bleeding during defecation; about 85–90% of cases occur in the posterior midline of the anus.

The good news is that not every case requires surgery. Many acute fissures can improve with stool softening, increased fiber and fluid intake, avoiding straining during bowel movements, and warm sitz baths. When symptoms persist or the fissure becomes chronic, doctors may consider anal fissure cream, other treatments, or surgery depending on the condition.

In this article, Tiptory helps readers understand how to treat anal fissures, how to relieve pain at home, when to use medication, and what signs indicate the need for a doctor’s visit. Especially, if the pain recurs after each bowel movement, addressing the root cause early can help break the vicious cycle of pain – spasm – difficulty healing – recurrent pain.

Part 1: How to treat anal fissures at home with medication

Tip 1: See a doctor to determine the cause

1. Get examined to confirm if it is an anal fissure

• When suffering from an anal fissure, pain or bleeding during defecation might immediately make one think of an anal fissure. However, these symptoms can also occur due to many other issues.

• The doctor will ask about symptoms, when they appeared, and the level of pain, and conduct an appropriate examination to determine the cause. Accurate diagnosis is the first step to choosing the right anal fissure treatment method.

2. Do not self-diagnose or only use topical creams

• Some conditions such as anal abscess, infection, or perianal injury can cause symptoms similar to anal fissures but require different treatment approaches.

• Therefore, it is not advisable to self-administer anal fissure cream for an extended period without a clear diagnosis, especially if there is severe pain, abnormal bleeding, or symptoms that do not improve.

3. Provide a full description of symptoms during the examination

• Inform your doctor about anal pain during defecation, how long the pain lasts after defecation, whether there is bleeding, and any constipation or hard stools if present.

• Also report when symptoms began, recurrence, and any unusual changes in the anal area.

• This information helps the doctor differentiate anal fissures from other causes and develop an appropriate treatment plan.

4. Seek early medical attention if symptoms are prolonged or severe

• Acute anal fissures can often improve with conservative treatment, but prolonged or recurrent cases may require prescription medication or more specialized treatments.

• If there is severe pain, heavy bleeding, a painful lump, fever, or symptoms do not subside, a medical examination is necessary instead of continuing self-treatment at home.

Tip 2: Warm sitz baths for pain relief

Soak the anal area in warm water

• Soaking the anus in warm water, also known as a sitz bath, can help soothe burning pain and relax the muscles around the anus.

• The water should be lukewarm, not too hot, to avoid irritation or damage to the sensitive skin.

• This measure is often used to help alleviate discomfort during anal fissure treatment.

Perform for about 20 minutes each time

1. Prepare a clean basin or tub with enough warm water to cover the anal area.

2. Soak for about 20 minutes each time, performing this about 2–3 times a day, especially when the anal area is painful or uncomfortable.

3. After soaking, gently pat the anal area dry, avoiding vigorous rubbing.

Relax anal muscles while soaking

• During the soak, every 5 minutes, you can consciously check and relax your anal muscles.

• You can gently try to clench your muscles as if trying to prevent a bowel movement, then focus on relaxing them completely.

• The goal is to reduce anal muscle spasms, thereby helping to relieve pain and facilitate anal fissure healing.

Notes for safe warm sitz baths

• Do not use excessively hot water and do not add soap, detergents, or scented products to the water.

• Warm sitz baths primarily help relieve pain and relax muscles, but do not replace treatment for the underlying cause of the anal fissure.

• If pain increases, bleeding is heavy, a painful lump appears, fever occurs, or symptoms do not improve, seek medical attention for evaluation rather than continuing only warm sitz baths.

Tip 3: Apply a warm compress when sitz baths are not possible

Warm compresses help reduce discomfort

• When it is not possible to take a warm sitz bath for anal fissures, a warm compress or heating pad can be used to apply warmth to the anal area.

• Warmth can help the muscles around the anus relax, thereby helping to reduce burning pain and discomfort.

Use moderate temperature

1. Set the heating pad to a medium heat level, avoiding excessively high temperatures as the injured anal area may be more sensitive than usual.

2. You can sit on the heating pad for a maximum of about 20 minutes at a time.

3. Check the skin during and after applying the compress; if you feel burning, excessive redness, or discomfort, stop using it.

Choose a convenient method for daily life

• Heating pads have the advantage of being easy to use while working or when unable to go to the bathroom, but they must be placed on a stable surface and used according to the device's instructions.

• This is a measure to help relieve anal fissure pain, but does not replace treatment for the underlying cause. If symptoms persist or recur, a doctor should evaluate to select an appropriate anal fissure treatment method.

Tip 4: Use topical medication as prescribed by a doctor

Topical medication can help relax anal muscles

• In some cases of anal fissures, doctors may prescribe topical medications to reduce anal muscle spasms.

• When anal muscle spasms are reduced, pain can improve, and the fissure has better conditions to heal.

• This is one of the anal fissure cream options used in treatment, especially when initial care measures are not sufficiently effective.

Use correctly and appropriately

1. Only use medication after it has been evaluated and prescribed by a doctor.

2. Apply the medication according to the prescribed dosage, location, and duration instructed by the doctor. Some regimens may require use twice daily for about 6 weeks, but the actual duration depends on the type of medication and the individual's condition.

3. Do not arbitrarily increase the dose, extend the duration of use, or switch to other medications without consulting your doctor.

Be patient for enough time to evaluate effectiveness

• Treating anal fissures usually does not yield immediate results. Fissures need time to heal, especially when anal muscle spasms persist.

• If pain, bleeding, or anal fissures recur despite using medication as directed, seek re-examination for the doctor to re-evaluate and adjust the treatment method.

Tip 5: Use anesthetic for pain relief

Topical anesthetics can help relieve pain

• If anal fissures cause severe pain, your doctor may prescribe a local anesthetic such as lidocaine to reduce pain, burning, and discomfort.

• The medication can be used with other anal fissure creams or as an alternative depending on the specific condition.

• Anesthetics primarily help control symptoms and do not directly heal the fissure. Therefore, it needs to be combined with the anal fissure treatment plan provided by the doctor.

Use as directed

1. Only use anesthetics when instructed by a doctor or healthcare professional.

2. Apply the correct amount to the correct location as prescribed; do not arbitrarily use more frequently or longer than recommended.

3. Do not use the medication on skin showing signs of infection or unusual lesions without prior evaluation by a doctor.

Monitor for irritation after application

• If burning, itching, redness, swelling, or noticeable irritation occurs after using the medication, stop use and inform your doctor.

• If pain worsens, bleeding increases, or fever or painful swelling around the anus appears, seek medical attention to find the cause instead of continuing to use only pain relievers.

Tip 6: Ask your doctor about stool softeners

Stool softeners help reduce pressure on the fissure

• When suffering from an anal fissure accompanied by constipation, hard stools can irritate or further injure the fissure with each bowel movement.

• Your doctor may consider laxatives or stool softeners if constipation makes bowel movements difficult and painful.

• The goal is to make stools softer and easier to pass through the anus, thereby reducing straining and allowing the fissure to heal. This is an important part of conservative anal fissure treatment.

Use medication as prescribed

1. Talk to your doctor if stools are consistently hard, bowel movements are difficult, or you strain a lot.

2. Use the correct type of medication, dosage, and duration as instructed. Do not self-purchase laxatives and use them for an extended period without determining the cause of constipation.

3. Combine adequate water intake and increased fiber in your diet if appropriate, as these are commonly recommended measures to help soften stools and facilitate bowel movements.

Prioritize pain relief during each bowel movement

• When stools are softer, defecation is usually easier and reduces pressure on the injured anal area.

• If there is still severe pain, bleeding, or the anal fissure does not heal despite controlling constipation, seek re-examination for your doctor to re-evaluate and adjust the treatment method.

Part 2: When is anal fissure surgery needed and its cost

Note 1: Consider Botox injections when necessary

Botox can reduce anal muscle spasms

• If anal fissures are prolonged and conservative treatments are ineffective, doctors may consider injecting Botox (botulinum toxin) into the anal sphincter.

• Botox temporarily reduces muscle activity, thereby limiting spasms and muscle tightening that cause pain.

• When spasms are controlled, pressure on the fissure can be reduced, facilitating fissure healing. This is a specialized treatment option for anal fissures.

Discuss thoroughly with your doctor before injection

1. Ask your doctor if Botox injection is suitable for your condition, especially if the anal fissure has been prolonged or recurrent.

2. Discuss the benefits, risks, recurrence potential, and alternative treatment methods before deciding.

3. Botox should not be considered the first option for all cases; treatment methods should be based on the severity of the disease and response to previous measures.

Note on recovery time

• After injection, the anal muscles need time to respond to the medication, and the fissure also needs time to heal.

• The original content mentions about 2 weeks of recovery, but the actual time may vary depending on the injection technique, the condition of the fissure, and the individual's health.

• If pain, bleeding, or symptoms do not improve after treatment, seek re-examination for your doctor to re-evaluate.

Note 2: Consider surgery when the condition recurs

Sphincterotomy surgery may be used for suitable cases

• If anal fissures are prolonged, recur multiple times, or do not respond to medication, doctors may consider lateral internal sphincterotomy surgery.

• This procedure reduces the contractile force of the sphincter muscle, thereby reducing pressure on the fissure and allowing it to heal.

• This method is highly effective for some cases of chronic anal fissures, but it is not a suitable option for everyone.

Discuss thoroughly before surgery

1. Ask your doctor if surgery is suitable for your condition and medical history.

2. Discuss the benefits, risks, recurrence potential, and other anal fissure treatment options before deciding.

3. If you have issues with bowel control, inform your doctor. Reducing sphincter activity may make fecal control more difficult for some people.

Prepare for the recovery phase

• Recovery time after surgery is usually about 2 weeks, but the healing rate may vary depending on the individual and the technique used.

• During this time, adhere to the doctor's care instructions, especially keeping stools soft and avoiding straining during bowel movements.

• If pain increases, abnormal bleeding, fever, or difficulty controlling bowel movements occur after surgery, contact a medical facility for evaluation.

Note 3: Consider flap surgery for severe fissures

Anal flap surgery for difficult-to-heal cases

• If anal fissures are very severe or the fissure does not heal despite other treatments, doctors may consider advancement flap surgery.

• This method uses healthy tissue from a suitable area to cover and help repair the fissured area, rather than directly affecting the anal sphincter.

• This can be a viable option in some cases of chronic, difficult-to-heal anal fissures, especially when there is a need to limit the risk of affecting bowel control function.

Discuss with your doctor before choosing

1. Ask your doctor if the severity and location of the fissure are suitable for the flap technique.

2. Discuss the benefits, risks, recovery time, and recurrence potential.

3. Compare with other anal fissure treatment methods before deciding on surgery.

Only consider when conventional treatment is not effective enough

• Flap creation is not the first-line treatment for all cases. The choice often depends on the extent of the damage, the duration of the condition, and the response to previous methods.

• If the fissure does not heal, pain persists, or it frequently recurs, a follow-up visit with a proctologist is recommended to determine the cause and choose an appropriate treatment plan.

Part 3: Effective ways to prevent recurring anal fissures

Tip 1: Drink enough water to prevent anal fissures

Drinking enough water helps limit constipation

• Dehydration can cause stools to become dry and hard, making bowel movements more difficult and increasing the need to strain. These factors can contribute to or worsen anal fissures.

• Staying hydrated helps soften stools, especially when consuming a high-fiber diet.

• Therefore, drinking enough water is a simple habit that can aid in treating anal fissures and limit recurrence in at-risk individuals.

Maintain adequate water intake daily

1. Drink water consistently throughout the day instead of waiting until you are thirsty.

2. Approximately 2,000 ml (8 cups) per day can be used as a reference point, but actual needs vary depending on weight, activity level, weather, and health status.

3. If you are very active or the weather is hot, your body may need more water to replenish lost fluids.

Combine water intake with a high-fiber diet

• Increasing water intake alone without paying attention to fiber may not be enough to improve constipation. It is advisable to combine water with green vegetables, fruits, whole grains, and appropriate fiber sources.

• When stools are soft and easier to pass, you will strain less, thereby reducing pressure on the injured anal area.

• If you drink enough water but still experience recurrent anal fissures, persistent constipation, or significant pain during bowel movements, you should consult a doctor to find the cause and appropriate treatment.

Tip 2: Increase fiber to soften stools

Fiber supplementation helps limit hard stools

• A diet with sufficient fiber helps increase stool bulk and improve its softness, thereby supporting easier bowel movements and reducing the need to strain.

• This is a crucial factor in treating anal fissures, while also helping to limit constipation – a common cause associated with anal fissures.

• Fiber should be supplemented regularly instead of only increasing intake when experiencing pain or constipation.

Prioritize high-fiber foods

1. Eat plenty of whole fruits instead of just drinking juice.

2. Supplement with various green vegetables, such as spinach, kale, cabbage, and other leafy greens.

3. Add beans and legumes to your meals.

4. You can also choose whole grains and other high-fiber foods to diversify your fiber sources.

Increase fiber gradually and drink enough water

• If you currently eat little fiber, increase your fiber intake gradually to allow your digestive system to adapt, avoiding bloating or discomfort.

• Drinking enough water is also very important because fiber needs water to help form soft, easy-to-pass stools.

• When stools are softer, defecation puts less pressure on the injured area, thereby helping anal fissures heal faster and reducing the risk of recurrence.

Do not strain during bowel movements

• Even with increased fiber, if you still have to strain hard or experience prolonged constipation, the anal fissure may continue to be irritated.

• If you experience chronic anal fissures, bleeding, or severe pain during bowel movements, you should see a doctor for evaluation instead of just adjusting your diet at home.

Tip 3: Don't hold back when you need to have a bowel movement

Go to the toilet as soon as your body signals

• When you feel the urge to defecate, you should go to the toilet promptly instead of trying to hold it in. Regularly delaying bowel movements can cause stool to remain in the colon longer and become dry and hard.

• Hard and difficult-to-pass stools can increase straining, irritate, or prolong the healing of anal fissures.

• Forming the habit of timely bowel movements is a simple step in treating anal fissures and preventing recurrence.

Don't hold it in due to busyness

1. When the urge to defecate arises, make time to go to the toilet instead of trying to delay it.

2. Create conditions for comfortable bowel movements, without rushing and without straining hard.

3. If you are often unable to have a bowel movement when needed, review your water intake, fiber intake, and daily lifestyle habits.

Keep stools soft to reduce pressure on the fissure

• Combining adequate water intake, sufficient fiber intake, and appropriate exercise helps maintain bowel motility and limit constipation.

• When stools are soft, bowel movements are easier, reducing friction and pressure on the injured anal area.

• If you have an anal fissure but still experience prolonged constipation, pain, or bleeding during bowel movements, you should consult a doctor for appropriate evaluation and treatment.

Tip 4: Limit foods that easily cause constipation

Reduce foods that can worsen constipation

• Constipation and hard stools can increase pressure on the anus, causing anal fissures or prolonging their healing.

• Instead of overly restricting your diet, you should monitor which foods cause you constipation and proactively adjust your portions.

• An appropriate diet is an important part of supporting anal fissure treatment and reducing the risk of recurrence.

Limit certain foods when they make it difficult for you to have a bowel movement

1. Dairy products: If you notice that cheese or other dairy products cause constipation, reduce your intake and replace them with other suitable food sources.

2. Chocolate: May need to be limited if excessive consumption leads to a lack of fiber in your diet or worsens your constipation.

3. Fried foods: Often low in fiber and can lead to an unbalanced diet if consumed regularly.

4. Red meat: Does not necessarily need to be eliminated completely, but should be eaten in moderation and combined with vegetables, fruits, whole grains, or other fiber sources.

Prioritize high-fiber foods instead of just avoiding certain dishes

• When adjusting your diet to prevent anal fissures, the focus should be on increasing green vegetables, whole fruits, legumes, and whole grains.

• Drinking enough water and regular exercise also help support the digestive system's function.

• If you have changed your diet but still experience constipation, hard stools, pain, or bleeding during bowel movements, you should see a doctor to find the cause instead of continuing to restrict many types of food on your own.

Tip 5: Exercise regularly to prevent constipation

Regular physical activity helps the intestines function better

• Maintaining regular physical activity can support bowel motility and help make bowel movements more regular.

• By limiting constipation and hard stools, pressure on the anal area also decreases, thereby contributing to the prevention of anal fissures.

• Appropriate exercise also supports the recovery process for individuals currently suffering from anal fissures, but it does not replace medical treatment when symptoms persist.

Maintain about 30 minutes of exercise daily

1. Aim for about 30 minutes of physical activity per day, depending on your physical condition and current activity level.

2. You can choose simple activities such as brisk walking, cycling, swimming, or gentle exercises.

3. If you are just starting, gradually increase the duration and intensity instead of overexerting yourself.

Combine exercise with healthy bowel habits

• Exercise will be more effective when accompanied by a diet rich in fiber, adequate water intake, and not holding back bowel movements.

• The goal is to maintain soft stools, regular bowel movements, and limit straining, thereby supporting anal fissure treatment and reducing the risk of recurrence.

• If anal fissures cause severe pain, prioritize activities that do not increase pain or pressure on the anal area and consult a doctor if symptoms do not improve.
