Hello, I evaluated your query thoroughly. Daflon does not cause constipation. First of all, have you consulted doctor and got diagnosed for hemorrhoids? Because what amount of your narration is there, I doubt for fissure more. My recommendations at present: • Proper examination by a consultant surgeon to get perfect diagnosis in form of fissure or hemorrhoid (which degree) • Managing diet with high fiber, green veg, whole grains, cereals, pulses, plenty of liquids to get soft, smooth, regular bowel evacuations daily • Isabgula husk help in many cases to be consumed 3 teaspoonfuls at night with glass of lukewarm water, dose titer adjustment in follow-up according to the progress • Avoid all oily, spicy, non veg, chilly, junk items • Sitz bath (sitting in a tub filled with lukewarm water 10 minutes each morning, evening, and especially after passing stools) helps a lot • Local application of Lidocaine (5%) jelly gives soothing effect • Keep the part clean, dry • Liberal use of anti-inflammatory drugs for pain relief • Avoid smoking/alcohol in any form/tight jeans • Avoid stress, anxiety • Have regular sound sleep of 7 to 8 hours • Avoid exposure to excess heat/sitting on hard surfaces/long drives • Keep ambulatory with regular walking, exercises, yoga • Keep your body weight under control Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Bhagyesh V. Patel
