2. Continuing for a long time; lingering; habitual.
(Webster's Revised Unabridged Dictionary)

Up to now I thought the term colon irritabile on my diagnostic report referred to the fact that right now, and only right now, my bowel was irritated. After a recent flare up I decided to look into the term and uncovered that it means I have a chronically irritated bowel, otherwise know as IBS (Irritated Bowel Syndrom) - a chronic disease. Yay. I'm so thrilled about this. Can you tell the sarcasm?
