Am anal fissure is a non-healing wound in your anus. It can be extremely painful and disrupt your life. Treatment consists of preventing further injury and helping your body heal by relaxing muscle tightness that cuts off blood supply to the wound. Initial treatment is with lifestyle changes and muscle-relaxing cream. Surgical options to relax your muscle include botox injection and cutting a small part of your sphincter muscle. Dr. Ofshteyn will go over all treatment options with you and help you decide on the best treatment.
