Hi everyone! I'm back!
I posted previously under 'Anal Exam' and have since been to my doctor. He says that I have a minor internal hemmorhoid (phew!) but, I still have a general question for this audience...he said that what I'm feeling during my self-exam is my sphincter. Is that a muscle, cartiledge, or a bone? What about my coccyx? Again, what I'm feeling is something roundish just inside my anal cavity (in the upper region).
Is it normal to feel something there? My doctor thinks so but, it's weird.
