i had success in healing of it but it was a long 5 years...that is four years is when i had enough of it that i finally signed up for surgery but then i crossed paths with macrobiotics and squatting that it seemed to turn things around for me. it took about year 5 to really just feel normal.
i think a big part of my problem was that i was so stressed out about going to poo that i just tightened up even more and well, i was tight assed to begin with, that it just made matters worse.
squatting and being open to yogic breathing while pooing and absolutely only going to poo on my body's time clock - not mine - helped some. combine this with diet and exercise, it complemented one another.
