I read this in a blog on here posted by ARSETS.-- Once you have cleared your bowels for the day, get a raw potato and cut a small piece, then shave it down to capsule size making it smooth. with gloves on or cling wrap insert the potato pellet into your rectum, it doesn't have to be too far and let it sit there until your next bowel motion. It will come out by itself.
i only needed to do this twice over two weeks and my chronic anal fissure was a thing of the past!
Very occasionally it flares up when i am stressed but it is not too hard for me to fix.
I do hope this helps you and more people find this painless way of healing such a nasty secret problem
