For the last week or so I have had quite a bit of pain from passing stools. There are large white lumps in my stool, which feel as if they are tearing my rectum as they pass. Its is not constipation as the rest of my stools are soft, although they have been a dark green color and foul smelling which is unusual. I am finding that this problem is worsening with time which is concerning.

I'm not sure if this has any relevance, but I also had some abdominal pain during intercourse last week. This pain seems to have passed so I passed it off as nothing.

Any help would be greatly appreciated
