I have pelvic floor dysfunction and had trouble with BMs prior to a fissure. I now have 2 fissures and it's nearly impossible (and this is after I got botox into the pelvic floor recently). I am thinking that, at least now, the isssue is probably my internal sphincter. Hence the interest in the LIS. I have noticed that for me, getting botox into the IS makes my pelvic floor cranky. Like I always feel like I need to have a BM so I tighten it to make this feeling go away. Has anyone with pelvic floor issues gotten LIS and found that it enabled them to heal?
