Why do i rarey poop ?! today i would have 12 days since my last visit to the bathroom and the problem is i feel no pain

Constipation: If this is a marked deviation from your usual bowel pattern, you should be evaluated by your physician or a gastroenterologist. I doubt a mechanical obstruction because of lack of pain, cramps, distension. It may simply be a chronically sluggish bowel pattern aggravated by lack of adequate fluid and fiber intake. You may be advised to take bowel conditioners like senokotS. Avoid laxatives.
