Shouldn’t that be a compacted BM?
I just googled my terminology for the “condition” and the “impacted” part is correct. (Just substitute “stool” for “BM”.) But I knew that and didn’t want to say it. Your word choice may be applicable too, but I’m not going to look that up. But I will compromise with you and go with, “impacted #2”. I don’t want to tell you what word is used for the proper medical terminology. Let’s just say they call it “_____ impaction”.
