The small hole you have is from a pilonidal cyst. Most drs will tell you they come from a hair gone wild. I had mine removed about a year ago and i'm doing great. They are called a cyst but that's not what they really are. They are not cancerous, so don't worry. The lucky ones like you and I have the small hole. The hole is where the cyst has attached itself to your skin. It's called a sinus, but basically acts as a drain. If you have'nt allready you will feel a lump about a inch above the hole on one of your cheeks. This lump will start to hurt as it feels up with puss and it will bust on it own and drain from the hole as puss and blood. It's stinks like something that comes out of the other hole back there but you will feel much better once it burst. Alot of people never have the hole and are forced to suffer. They say the pain can be as bad as delivering a baby. I would burst mine myself most of the time to do away with the pain. Just simply push down on the lump when it starts to hurt and it will burst. I almost fainted the first time it burst, about two tablespoons of puss came out at once. I finally went to the doctor after about 6 months of not knowing what it was.
When you go to the doctor you will have several options. Sometimes they will lance it and drain it. For some this works and it never comes back. For others like me it does'nt, so surgical removal is the other option. There are two types of surgery. Open wound and closed wound. Open wound is where they remove the cyst and do not stitch it closed. It has to be packed a couple times a day and takes 4 to 8 weeks to heel. Most people can't miss work that long so they go with the closed wound surgery. The closed wound is stitched closed and heals in 2 to 3 weeks. They say the closed wound has alot greater risk of infection because like a burn this has to heels from the inside out. The cyst actually digs about 3 to 4 inches inside you, so it's a deep incision. You will need a special cushion to sit on after the surgery( coccyx cushion). If you elect not to have it removed you will weaken your bodies ability to fight of colds because your immune system will always be fighting this pilonidal cyst.
Here is a great website forum for people who have this terrible cyst.
