This happened quite a while ago but I've just found the photo.
I had a 'spot on my head for about 20 years, I didn't like it as if my hair parted the wrong way it would look bald. One day I noticed that it had gone soft, I think I bumped my head about a fortnight before, a few days after that I noticed that it felt wet. My DH looked - he is NOT a sporner - and confirmed that it had popped. What joy!
He gave it a little squeeze but wouldn't take pictures. I took the one below myself, excuse the greasy hair.
I kept up the squeezing/cleaning and two days later in the loo at work I decided to really have a big squeeze. Oh my, it was amazing. I saw a fountain of pus explode from my head and land on the mirror. It was the best day of my life.
No pics of the mirror as I didn't have my phone. Here he is on the first night though.
It's completely gone now and the hair has grown back.
