Can internal hemmoroids cause your stool to have ridges in it on more than one side when the stool is softer? I also have blood on and sometimes in my stool. I had it checked out a couple years ago and my GP said I had an internal hemmoroid. I did 2 FOB tests and I think out of six slides 2 were positive, but doc didn't seem concerned after doing the rectal exam. I've also noticed my stools are a little smaller. Anyone have any ideas? Thanks!
