Hello, A confirmation is must for the diagnosis by a consultant surgeon, but here are the salient guidelines for a probable cause of a fissure. - drink more liquids - high fiber diet with green leafy veg, cereals, pulses, legumes - avoid spices, non-veg, junk food stuffs - sitz bath (sitting in a tub filled with lukewarm water) - local application of xylocaine jelly over anal region - bulk-forming laxative as Ispaghula husk or Psyllium husk with warm water at bed time - avoid smoking or alcohol if consuming - avoid anal intercourse (if involved) Fix an appointment with your primary care provider for examination and further guidelines. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Bhagyesh V. Patel, General Surgeon
