Oh.... that's bad.... But I believe that you are in a better situation than mine.
After LIS, my constipation did not go away. Yeah, I've been scaring myself using google too. I think I have atonic colon. With it you generally suffer many many years with constipation, using lots of laxatives, then when nothing works, you just take out colon out of your body. Looks like this is my future and your abscesses is nothing compare to what I might have.
So, don't be depressed too much. They know what is wrong and how to fix it.
Mine, they don't know why and how to fix. So you are a lot better situation.
