Hey! I'm a 21 year old male. I've had problems with discomfort around my tailbone area for as long as i can remember. I was born with a small opening about 1 inch above my anus. After some research, I'm assuming this is called a "sacral dimple". When I was younger, the doctor said it was nothing to worry about. About three years ago, I developed a small pimple on the outer edge of my sacral dimple. It hurt so bad and I went to the doctor. He diagnosed it as a Pilonidal cyst and said there was nothing I could do unless I wanted to get surgery. I decided to do nothing, and a few days later it just went away. It never drained, it never "popped" it just disappeared. It came back around a year later, again, it was small, very painful but nothing I could not live with and after about a week it went away. Fast forward to this year, and it's back again and it is bigger than it has ever been. It's about the side of a half dollar piece, and very red and swolen. It hurts mostly when pressure is applied but it still kind of aches when I'm laying on my stomach or standing up. It's been there for about a week as of me typing this. It is slowly getting bigger and harder. I know I should go to the doctor but I wanted to seek some guidance here first. So, since I have a sacral dimple, is it possible that it is just infected and it is throwing these abcesses out? If so, is that a pilonidal abcess. What's the difference? I've read a lot on this site and people talk about drainage and multiple sinuses and I've never had any sort of drainage or anything like that. Is an infected sacral dimple and a pilonidal cyst the same thing? My doctor seems to think it is. Should I seek another doctor? If it's not the same, what would be the treatment for my case? Thanks!
