Painful: The man took to Reddit to show off his unusual backside
A man who lost his butt crack to an unpleasant disease has shared his story of life without this vital piece of anatomy.
The condition causes painful cysts to occur at the bottom of the tailbone and they can become infected and full of pus.
"I’ve had multiple surgeries on it and instead of the usual procedure which involves letting it heal, mine was so bad that a plastic surgeon had to close it up," he said.
"They keep coming back, and it’ll probably just get worse as I age."
Reddit: Users shared their problems with similar conditions
Thankfully it hasn't effected his love life: “I’m married, and she’s cool with it.”
The AMA also allowed other pilonidal cyst sufferers to open up about their painful condition. One user ThePhlor said: "Yeesh. Had pilonidal cysts last year and got surgery this summer to remove it and that sucked...but not nearly as bad as this. Hope things get better."
While another said: "I had a pilonidal cyst removed when I was about 14.
"It was caused by hair follicles growing into my skin because apparently when the skin fused in the womb it overlapped a little extra.
"There must be a way to permanently solve your problem. I have never heard of them coming back once the tissue is removed."
