Your diagnosis is Chronic anal fissure and you have undergone surgery without relief. Continuous spasms of anal sphincter decreases blood supply and causes pain. So, immediate symptom relief is with topical vasodilators like 0.4% Nitroglycerin (Rectiv) or 2% Diltiazem / Nifedipine. Applied directly to the anal canal to decrease resting pressure and improve healing blood flow. Remember, Nitroglycerin can cause headaches as a side effect.
Soaking your anus area in a shallow, warm water bath for 15–20 minutes 2 to 3 times a day. This relaxes the spasming sphincter muscle and safely eases sharp post-defecation pain.
Daily use of bulk-forming fiber supplements (like psyllium) paired with osmotic stool softeners (like MiraLAX or docusate). This prevents straining, which is essential to prevent tearing the fragile, healing tissue.
For severe pain, apply Lidocaine around anus. This can ease bowel movements.
Avoid codeine-based painkillers, as they cause severe constipation.
Next Steps
Advanced Non-Surgical Treatments are available like Botox Injections. A gastroenterologist or colorectal surgeon can inject Botulinum toxin (Botox) directly into the internal anal sphincter muscle. This temporarily paralyzes the muscle for 2 to 3 months, completely breaking the spasm cycle and allowing blood flow to repair the tissue. It is highly effective.
Health Tips
Medical treatments fail when the original cause—constipation and straining—is not addressed.
Drink 2 to 3 liters (8 to 10 glasses) of water daily so your body can adequately soften stools.
A diet of whole grains, leafy vegetables, and fresh fruits (like papayas and prunes).
Use a toilet step stool to lift your knees into a natural squatting position. This straightens the rectum and allows stool to pass with minimal effort.
Avoid dry, rough toilet paper. Use a bidet or alcohol-free wet wipes, and gently pat the area dry without rubbing.
