I am a 25 year old male healthy, occasional smoker and a homosexual with no anal intercourse since i started having issues 8 weeks ago. I had a colonoscopy 4 days ago due to my severe constipation over the past 2 months, it started with mucous and then my bowels completely stopped evacuating to the point where my stomach was distended and and nothing would help...enemas laxatives etched. I went to the we because i couldn't urinate due to fecal impact ion but with morphine and saline i finally urinated and had very small movements that were flat, strings and would des integrate once out. Needless to say i went on a heavy miralax regiment started occasionally having diharreah movements and finally had my colonoscopy. The took biopsies of what looks like an minor 2cm ulcer, i haven't gotten results or had a movement yet. But just now i felt the urge to go and was excited but I just passed a giant blood clot that almost looked like some sort of mass. i am so very confused and anxiously scared. if anyone has had the same issue i could use some clarification and help asap.again Im a healthy occasional smoking 25 yr old male.
