Hi also just want to ask sometimes when i poop i feel a kinda sharp feeling in my anus after. do you think this green small spot and sharp feel has some kind of a connection?

Not connected: Green spots in the stool have to do with what you eat and are probably not connected to sharp pains. Sharp pains with having a bowel movement have to do with either the stool being too hard or possibly a hemorrhoid or other irritation in the rectum. Try to get your stools soft by drinking plenty of water and eating foods with high fiber content.
