If done by an experienced surgeon, the chances of anything serious happening is very very low. Botox is very well studied over the years, chances of adverse side effects is minimal, especially at the dose used on the sphincter. It wears off in a few months so it's reversible too, unlike surgery. The success rate that's stated for it varies from doctor to doctor, mine said it was 80%. Success rate goes down the longer a fissure has been around and developed scar tissue and other structures around it.
8/16-12/16: Fissure due to antibiotics
5/17: Botox to sphincter, fissure healed
9/19: Trigger point injections and pudendal nerve block
11/19: Botox to pelvic floor
8/20: Botox to pelvic floor in new location.
On and off in pelvic physical therapy
