My anal fissure wasn't severe, as in there was no bleeding and no pain most time except during potty but it wasn't severe pain. From the picture I took of my fissure, I saw that there were 4 tear on my anus(exterior). I've always cleaned my ass the Indian way(from India) after potty which is washing your ass with water instead of toilet paper. I guess that helped my fissure from getting worse.
I am gay and never had problem with anal fissure until about a year back. I tried neosporin, vaseline, some hemoroid cream but they weren't any good. With time my fissure would heal but only from surface and would tear back the next time I've big potty or anal sex.
So after reading about Organic coconut oil in this forum, I tried Organic coconut oil which was pure extra virgin which I ordered from amazon. I used it twice and sometimes thrice a day, usually at morning and before sleeping. I would just smear it in my ass and also stick some inside my ass. Exactly 8 days after my anal fissure healed and I can feel that it's a proper healing and not just surface healing. I feel like I've a new anus. I've decided to continue using coconut oil in my ass, not as frequently but whenever I've time. My ass really feels good now.
Point to remember - wash your ass with hot water(not too hot) after every potty. The coconut oil should be organic and extra virgin.
I hope this remedy helps some of you guys out there.
