I am a male and have a hardening just outside my anus. It begins just outside my sphincter and goes up my left side about an inch. It is on  my left side only. It wasnt painful at first, now it is a little. I am a 53 year old male in excellent health. I did have pilonital cysts removed when I was 21. Since then no problems.
