Pat,
If the pain moved along like that, I tend to think it was not really a partial blockages. I don't think they move like that. At least mine doesn't. The pain is focussed, in waves, and in the very spot my ileus was stapled back together. Once it starts to clear, the pain gets less, stays in waves, and eventually goes away. No diareah or constipation associated with it. During the full blockage, I have no actual bowel movements but once it clears, things return to normal.
