Please have a doctor check you out immediately. It sounds like you are impacted. You will be so relieved once they take care of that initial blockage. Then all the stuff you have tried to use will just empty you out.
Andy was on a bowel program that worked. The main thing: 1/2 cup prune juice, warmed up, mixed with 4 tablespoons of milk of magnesia. He had it every other night before bed. Works like a charm. Warming the prune juice seems to be the trick. He was also on a daily stool softener (twice a day) AND Senna, once a day, which is a liquid. Andy was a big guy so I would check with a health professional for dosages. He had lost all pushing power, and we used a sling and his lift to hover him over the toilet. It was the prune juice cocktail that kept him regular. Also, our radar went up for anything that would be potentially binding, like tylenol with codiene and other strong pain meds. These he would avoid. We used all this when he was still on regular food. At the end, when we were trying formula, we were having to readjust to compensate for whatever was in that stuff. You know, he thought the walking thing was going to be the big bummer in this disease. He quickly realized it was the pooping thing. Never did he ever imagine the troubles from that end. Hope my rambling helps someone out there. Blessings, Pam
