Yes, its very common for the prep to cause inflammation and they call it prep induced inflammation. I freaked out when I saw my pictures because I had inflammation all through the colon and thought I had pancolitis when in fact I just have proctosigmoiditis. But the inflammation was prep induced.
Did they see any ulcerations/granulations on your scope when they gave the dx? My dx was not done through biopsy (they tried) but through a visual observance between two gi doctors (I still question my dx because of this too) but my pics are pretty clear that there was something nasty going on in there.
I don't take any probiotics yet because they are currently putting me through tests to see if my medications are helping with my inflammation and they don't want anything to disturb the balances.
There are many on here though that I'm sure will be by to give you their experience on probiotics since more than half of our regulars take them.
