I have had constipation for years, about three mos ago my physician started me on Liness, I started on a low dose and have progressed to a higher 290mg dose for aobut three mos. For the last two days I have had little or no bowl movement with even using a supposotiry. I have due to talking to the Dr. taken some sena tonight and still have no feeling that I have to go. Would it be that I just don t need to go or does it mean something else. My stomach doesn t seem distended (I am not quite sure what that means but I don t feel any swelling, tenderness or pain) Should I just wait till morning and see what happens or should I do something tonight. It is 9:30 pm eastern standard time. Since I have no pain but a lot of stress with thinking I may have some sort of blockage I don t know what to do.
