I'm fairly certain I now know why I occasionally get an anal fissure, which tends to last about a week.
There are times -- many times, actually, and for prolonged periods -- when I slouch way down in my office chair. I work from home, so I obviously have far more freedom and privacy than if I were in a regular "public" office.
I'm now almost positive that this prolonged, strained angle of sitting puts undue and unusual pressure on my lower body; i.e., my rectal area. And I have a feel that, over time, that constitutes a form of trauma.
As we know, anal fissures are most often caused by trauma to the anal canal. The usual suspects are hard stools; childbirth; and perhaps intentional trauma to that area via anal sex or the insertion of other objects.
But in my case, again, I'm quite certain now that this prolonged slouching -- where sometimes my tailbone is virtually resting on the front edge of the chair -- is the cause of my fissure.
I doubt anyone else has had a similar experience, but I'd love to hear about it if you have. Thanks.
