I am 81, female, no bowel movement for 5 days, severe pain in my back going around to hips, minor burning with urination, slightly nauseated, took magnesium citrate laxative 2 days ago and still nothing, sense of fullness, don't take any pain medication, always have a bowel movement 2 or 3 times a day, urine is just dribbles now, not drinking as much water as usual because I am afraid of filling up since nothing is coming out. what do I do to have a bowel movement NOW? I am not overweight, non smoker, high blood pressure and I take a purple pill when I am going to eat something spicy. I am about 5'5 and 125 pounds, not as active since broken hip last year, but still live alone and care for me and my 5 house dogs, 3 outside dogs, and hang my laundry out on line, walk to get my mail, I do not drive and am careful about what goes in my body. bought a Fleets enema, but did not use it because I can't lay on my side and the package said not to use if over 65.
