sounRAB like it's hemorrhoiRAB. or rectal inflammation from whatever source.
You should, however, get it checked out...get your doc to send you to a gastro doc if whatever treatment doesn't help. A look-see would be better than just a finger up the butt.
Have you taken a look externally yourself? Squatting over a mirror can at least give you an idea...if things are red and swollen, it's possibly external hemmies. They can be dealt with by using even over the counter hydrocortisone cream.
