The rectum is that bitta intestine what connects to your butt right?
I had trouble with it this week. I never used doc Google but figured that I had stomach flu coz it come with fever - I think this is called norovirus coz I had it before many times.
Did yoga for it and drank loadsa water/herb teas and after 5 days it calmed down.
If yous talking about constipation, yoga will sort it plus fiber for morning nosh.
