I'm a vet of a fissure and roids, I had surgery for a fissure after about two years of pain, pain so bad it made me want to vomit, I've been great since the surgery.
As for roids and or fissure, the best thing I've read here is fiber, fiber, fiber.....take metamucil, and eat prunes, no strain, no pain. Nothing like a two flush, no wipe dump to keep things in order.
Prunes are some kind of natural stool softner and work wonders, I eat a handful every day.
I have also found that riding helps, not the fact that you are sitting on a tiny hard seat, but the fact that I am active, being active helps with being regular, being regular keeps you from staining.
