I know your pain! I suffered from an anal fissure for about two whole months (if not longer). I searched the internet daily and tried everything you can think of to help me heal! Every time I would use the toilet, I would feel the fissure on my left side tear. It would be just a little bright red blood most of the time, but once or twice the toilet would look as if it were full of blood. The one thing most people don't understand is that when you up your fiber intake, you also need to up your water intake. Fiber bulks up your feces, it doesn't soften it. Both fiber and water are a big help, but I found the only thing that has ever helped me is Miralax. I'm a 24 year old female and I weigh about 140. The cap is the measuring spoon and I only fill it about halfway. In about a week my anal fissure was healed! I've been taking the Miralax for about 3 weeks now. It says it's okay for long-term use, but I am thinkning about weaning myself off of it. I don't want to take it for the rest of my life! It's completely tasteless and dissolves completely in anything! I highly recommend it! Good luck everyone
