i haven't passed a bowel movement in four days and even though I feel that I have to, I don't. Its usually gas. And I get stomach aches, feel as though I have to go, but again, I don't. It ends up being gas. I'm not on any prescribed medication. Although, I am taking two motrins (200 mg/each) a day for 3 days for an achy neck and headaches. I feel bloated, though I'm not and just annoyed. Not sure if I can take a laxative if I'm taking Motrin.
