A few years ago I definitely had a mild case of C. diff from an antibiotic.Months after that, I had problem with a little fecal incontinence, pressure like I had to go but couldn't, NEVER ANY PAIN, BLOOD, ETC. Maybe I had mucous. A gastro doc called it IBS without any tests.Finally, one of their nurses just told me to take Miralax, which I do. Most of the time, it makes me go, sometimes several times a day. No diarhea. Sometimes just small pieces come out when I urinate and then when I wipe myself, it's all messy because the last piece refuses to drop out. Still never any pain, etc. I never can figure out how much Miralax to take to get it exactly right.Does this sound like I actually have IBS or could it just be my age-69- or because I take lots of meds for depression? Nobody ever cares about what's happening in other departments. I also take two thyroid meds as I had my thyroid removed.Does this sound like a condition one could call IBS? Are there any tests that would give a definitive diagnosis?How does one get a correct diagnosis?
