Hi. Thanks for your query. Noted your history of bleeding with bowel movements for 3 days and have heroine too which causes constipation increasing the anal fissure problem. I would advise you the following: High fiber diet. Avoid all the foods and beverages and stress-like conditions which gives constipation. Laxative for softening the stool- never allow the dose too much to cause liquid stools. Sitz bath- very important- just before passing a stool and after passing a stool. Clean the area very clear of the fecal soiling that remains after cleaning; use cotton soaked in the same water to clean. You can apply liquid povidone iodine locally. Apply nothing else. 5 day course of an antibiotic on prescription of a local Doctor. Add probiotics and multivitamins. Avoid stress and mental tensions at any cost; this is a very important factor.
