Crohn's disease and ulcerative colitis warriors suffer from a number of different symptoms, and I have written about more than a few. One symptom that I get more often than not is tenesmus. Imagine going to the restroom over and over and over ... only to sit in pain with nothing really happening. Possibly you had bowel urgency in the morning but your body tells you that you're not finished yet, even if there's nothing left to do. You're left sitting there, with spasms and the feeling that you have to go when nothing comes out but bloody mucus and gas. Tenesmus is a common symptom of IBD, Crohn's disease, and ulcerative colitis and can make the day-to-day with IBD quite miserable in the restroom. What is tenesmus? Tenesmus is the feeling of needing to go to the bathroom, of your body telling you that you need a bowel movement, and of not having or needing one.
