I have bad constipation and am looking for ways to stop it and help ease the pain?

Some other disease?: Each person with constipation needs to be sure there is no other disease causing it. If constipation is just due to slow movement of the food and poop through the gut, things to try are vegetables, prune juice, prunes, fiber-plus-water, polyethylene glycol, Senokot or other senna, milk of magnesia, etc... Make a symptom and "laxatives" diary for the doctor, who might try a drug like Linzess.
