That's exactly right, you can perforate the intestine if it's inflamed. But, one fellow on here also posted that if there is a spot of inflammation it might be encapsulated because the body does that and doing a biopsy (which I had)can disturb that and I do believe that is a risk but what can you do when you need to find out. The biopsy was negative with a grouping of like cells but I believe if it were not for LC it might have been cancerous. I still have a reminder from time to time that it is still there. Soy sauce or horseradish makes it hurt so I have to watch that because obviously that spot is still there.
I believe it was a combination of stress and antibiotic use that could have caused it. Many antibiotics these these days list ulcerative Colitis (among other things) as a side effect.
