I don't get tired or expressing the fact that a fissure while will not go away immediately but for the lucky ones, they definitely get better, with the proper care and management, trial and error a routine you can stick with, it does gets better, eventually the better days will turn into weeks and then now like me two months, after six of suffering.
Yes is set back but no losing hope will bring you back in track and never get as worst as in the beginning unless you really are so far gone with a chronic fissure that only surgery will fix it.
And surgery should always be the last solution to the problem, because even when surgery helps many is also those that will not.
You will never know in which group you will be until you have it.
but things will get better, life can have some normacy with a more manageable fissure.
