Initial treatment for an anal fissure is good bowel habits and nifedipine ointment. If that fails, two surgical options exist. Dr. Ofshteyn can inject botox into your anal muscle to help it relax and allow for healing. If that does not work, Dr. Ofshteyn can perform a lateral internal sphincterotomy, where a small part of the muscle is cut to allow the rest of the anus to relax and heal. Dr. Ofshteyn will work together with you to help your body find a way to heal.
