Nothing impressive, but I'll share
When I was younger, I suffered terribly from Athletes foot which would not stop it's relentless itching, so I'd often squirt deodorant in the raw flesh and to have a severe burning sensation which would make me really grimace. The pain lasted for seconds, the itching would stop for hours.

But my favourite was self lancing my infected thumb. After peeling off a nail, I inevitably tore it off past the part where skin and nail meet. This lead to a rather nasty infection which was unbelievably tender to touch and ballooned like a red grape. A trip to the doctor was necessary I thought as it was only seeming to get worse. Which the doctor decided to treat this with a course of antibiotics as opposed to lancing to relieve the pressure.
A couple of days later my swollen thumb was not subsided. I sat on the bus on my way to college, with my index and thumb from my other hand holding onto the swollen digit. A jolt on the bus caused me to squeeze rather hard and a stream of pus, the colour which can only be describer as "Head and Shoulders lime" jetted out onto the chair in front of me. I felt a snap in my thumb as the delicate skin finally broke from the pressure.

I was so happy that day.
