Hello. Has anyone here had experiences with anal fissure surgery? I am scheduled for cutting of the interior sphincter muscle (excuse spelling & my memory lapse on exact terminology of procedure). Has it been succesful or not? Theory is that cutting the muscle will along blood flow & healing of the fissure. The fissure resulted from 2 impacted colon procedures last fall. No matter what doctor I saw, no matter what I took or did nothing has helped in these last 8.5 painful months. I took analpram, nitrogylcerin creme, warm water swimming & walking, high fiber & water diet, Miralax & now Zelnorm. I've had x-rays, 0 ring tracking tests, colonoscopy, etc. No reasons have been found for this to happen, but also no reason as to why I haven't healed. Outrageously painful episodes have gotten worse & more frequent & last week I pulled my lower back muscles during an IBS attack. Between fibro & other problems the entire area feels like hot broken glass on the outside of the skin & inside. A person on another list wrote to say she'd had the surgery & now has no feeling in her rectal area. Any & all comments are welcome. I have confidence in this surgeon, but am more than open to other opinions & real life experiences. Thanks so much! Best thoughts to all.
