I also have RH and Im waiting to do biofeedback. Im hoping they focus on re-establishing the sensory thresholds through balloon training as I believe this is much more difficult to rectify than PFD! I also have PFD but I think I have somewhat fixed this myself by being aware and trying to relax the pelvic floor. I think however its impossible for your anal sphincter muscles to relax fully unless you get a sufficiently strong urge - which for those of us with RH never really happens!
For me, I cant get the urge if my stool is too loose - so I try to cut back on Miralax, but then it just stops moving through the colon entirely. Such a difficult balancing act.
I have read that Sacral Nerve Stimulation can possibly help with RH.
But yes I have many times contemplated that having a bag would be much easier than managing this!
