I've had a growth on the top of my anal opening for several years. It first came to my notice through pain on wiping. On further inspection, it became clear that a hard growth had installed itself adjacent to the anal passage. This body is immovable but periodically submerges in a type of crater or shallow second hole above the real one. Accordingly, it can flare up and became painful and irritated much as it can subside and be nearly invisible to the naked eye. This is the problem which stymied my attempts to provide a visual cue for a colo-rectal surgeon who examined me. I showed photos on my phone, but they informed me that they couldn't see anything and wouldn't proceed to a surgical solution. They did indicate some internal hemorrhoids and offered a ligation for those, by my pain problem is primarily related to this external object. I took two photos of the issue today and circled them in MS Paint for maximum clarification.
