Been suffering with an anal fissure for about 1 year now. Got a LIS+Fissurectomy last July which did not cure me, as the LIS cut was too conservative, and the pressure in my internal sphincter is still too high to allow proper blood flow, hence healing. I stumbled upon some researches showing how antibiotics (oral and topical) would actually help greatly with fissure healing and symptoms. In this study they talk about topical Metronidazole specifically, which would work by killing anti-gram bacterias who colonised the wound, making it chronic. Did you guys ever tried this approach? Any useful experience that you would like to share? I would love to give this therapy a try, since I got nothing to lose at this point.
