hello, i have got an acne on the top buttocks crack, it is flat, and many times starts bleeding or pus+blood, i had pimples , in that area one year back, but this one used to get settled down and again bleed/pus, now i am really worried if it is pilonidal cyst , and its been long now, it does not hurt. it bleeds when i sit for long time.
