I thought I usually recommend Magnesium to alter stool consistency. That may or may not effect pain. Many IBSers still have pain issues even if they can normalize the stool consistency.Usually I recommend peppermint or antispasmodics or low dose antidepressants for the pain that people call spasms.It can also be hard to know what is a colon full of stool and what is just how you are sensing things. Some people can feel full and bloated even if the colon is completely empty. Much of IBS is inappropriate nerve signals.It is hard to know what the incomplete and pain signals are from (often it is more in the nervous system then in the colon muscles).If you think you have pelvic floor issues that is usually treated with biofeedback to retrain the muscles, not just stool consistency medications. I don't know of a do it yourself version as I don't know if you can get the right info without the biofeedback (you might call up a teaching hospital as a lot of them will do reduced rate testing for people who can't afford it as most of them are charity hospitals).You can do regular kegels and try to see if you can sense tense vs relaxed on your own, but that doesn't seem like it works that well for the learning to relax them. It is more for toning the muscles, not when to tense and when to relax signals.I don't know if the home hypnotherapy will work specifically on pelvic floor muscles, but it often does help with all the other discomforts and while fairly expensive they cost about the same as one session with a hypnotherapist if you have to pay for it yourself and most in patient hypnotherapy programs require about 7 visits.
