I've had mine for at least 2 months now. At first, there was pain during a BM sometimes and sporadic blood, and at times spasms later in the day. It seemed to go away at first, then came roaring back while I was training and was having way too much fiber along with too little fat. After seeing a doctor and being advised to eat more fiber against my better judgement, along with a Docusate stool softener I wish I could yank from my hands, I literally tore my anus apart. The spasms lasted the entire day, putting me temporarily out of work because of the severity.
That was a week and a half ago. Since then, I've found this site and have hope again. Milk of Magnesia, Ibuprofen, less fiber, chewing thoroughly, avoiding power lifting, sitz showers, and having lots of oils have given me my first 2 days without a retear! Or at least without blood and the pain of tearing. The spasms still put me out but are lessening, and my sentinel pile is big enough to think about naming it. But I now have hope. I'm 27, and the minor tear healed before, so I'm hoping the present ones will now too.
Side note - Milk of Magnesia overnight is better than a sauna. Lost 5lbs of water weight. Kinda nice to know for future reference.
