paper cut like sore between buttocks.

[temarisand333]

For the past 3 months I have had this really odd thing inside of my buttcrack right in the center. I seem to have this strange raw red cut that starts at my tailbone and ends right above my anus. The cut on my skin like a paper cut and the skin around the top of my buttocks around the scar was red and sore like when skin is rubbed together to much.It was like that for about two months.  now the red skin around the sore has changed into grayish color. it dos not hurt nor do I feel any skin irritation like before but the discolrstion concerns me. could it just be healing or is it another skin issue.
