Yes, I have had this happen before. I had terrible difficulty having a bowel movement and it looked similar to what you describe. I had three partial obstruction. The nurses, etc. kept saying that there was no way that I could have one (this was prior to a surgery) as i would be way too sick and would have ended up in the hospital vomiting, fever and severe pain. Well, I had all of that and they wouldn't believe me. It was of course due to adhesions.

My bowel movements are very skinny and shaped like a pencil. This disturbs me because I am thinking the colon must be obstructed in some way. Anybody else have this? Sometimes they are totally flat.
