Hi, I havent participated in this group for a long time. I am chronically constipated along with some other medical issues. I believe that my constipation is due to Pelvic floor dysfunction. This means that the muscles down below are way too tight. I have been through physical therapy, and biofeedback..none of wjich have helped all that much. I am wondering if this drug may be an answer for me. what 'type' of constipation is Zelnorm indicated for?
