Hello, I have relized that I have a small hole about 5cm away from my anus and since I read around a bit, I think it might be a "sacral dimple" or "pinodinal dimple", something of that kind. It is not swelled up, it was jsut starting to itch about 3-4 days ago, and now I relized it was a hole. What should I do, and what is it actually?
(It is only about 1.5mm wide, no blood, no nothing, just irritation now)
