I find your post very interesting. As I've got older my anal sphincter muscles have got weaker and I've experience several very distressing episodes of faecal urgency. Fortuntaley no accidents (yet) but I've "been" in places I would never have managed it before. So I think botox may well help you. I am now religiously doing Kedgel exercises to rebuild the strength of those muscles to give me more control/less urgency. Rather than having to do exercises I expect your botox will just wear off, by which time you will hopefully have got used to going in places you otherwise would find difficult. I wish you the best of luck with it all.
