Hi. First of all you have to consult a General Surgeon to have a per rectal examination to confirm whether this is due to an anal fissure or piles or both. The pain you had indicates you have a fissure which causes pain as well as bleeding. 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. Continue this for 3 weeks and most probably you may not need surgery. If the results are positive you have to continue doing all this and take proper care.
