I never knew I had sinuses there
I'd found it uncomfortable sitting in the car for a while, a pain in my bottom suddenly intensifying, and the same was true if I sat in bed reading at night. Sometimes I'd wake up and find blood on the sheet or in my boxers (I'm a chap) and couldn't understand why.

After a few months of this I found myself in such pain that I went to see the doctor. I explained the situation and he asked to have a look.

"It's a pilonidal sinus," he said. Basically you have sinuses all over your body, not just in your nose and head, and the sinus in my backside had become the home of an ingrowing hair. The hair grows into the sinus, which tries to repel the intruder by making a lot of pus, but this becomes infected, forms an abscess, and when this pops the blood and pus comes back out. How nice. The only treatment was surgery, and a night in the hospital.

Afterwards I couldn't sit for a week, could barely walk, and didn't go back to work for three weeks. The operation was eleven or twelve years ago now and I still have a scar running down my bottom that looks like a zip.

Here's an idea of what it looks like after the op (this isn't me by the way): pilonidalcystpictures.net/Pilonidal-Cyst-Disease.php

Oh my.
I really wish I hadn't looked at that. It looks like a really cheap pizza.

Yep
Had to have a district nurse come round every few days to change dressings etc.

It's more like "hello doctor? I'd like my arse cheek back please"

When I worked in hospitals I looked after loads of blokes (never women) with those.
They were often professional drivers. A bit overweight, sitting down a lot, sweaty, ignoring the bumcrack soreness until it became really unbearable...

Last year I chatted to a lorry driver at a car boot sale and we got on to the subject of abscesses, as you do.

I advised him never to ignore soreness in his arsecrack area and he was so grateful that he sold me a digital camera with no lead or accessories for £1. Result!

Nice picture!
Just to be a massive pedant, you don't have sinuses all over your body like the ones behind your nose. 'Sinus' just means a void, sac or channel (sometimes full of fluid). In your case, your arse sinus was created by the accumulation of pussy liquids.
