I Have Pain Sitting, I Went To A Gastroentroligist, He

I have pain sitting, I went to a gastroentroligist, he gave me a script for a anal suppository, I took it for 2 weeks, no more bleeding, but sitting is a nightmare(half the time)...I have a colonostpy scheduled in 11 days to see what's going on....I tries hemroid cream, and it started bleeding again, so, no more cream...Just petroleam jelly...Any Idea's.....
