It was constipation that got me in to see the doctor...that's when I was diganosed with UC 5 months later. I was told the end of my colon was swollen. After the colonoscopy I was started on Masaline enema once at bed time. The constipation didn't come back.
Did your doc check for swelling? Are you taking enemas or suppositores? If your swollen the laxitive isn't going to help the casue of the consitpation.
