I once got a metal splinter in my thumb and thought I'd got it all out. The next day my thumb was huge and throbbing like buggery (well I assume buggery would be that painful).
I went to A&E and a nice young trainee doctor examined it and she said "I think we'll just lance that but I'll get a second opinion from a senior doctor first"
I was quite relieved to hear that but when the senior doc came over he looked at it and said "the nail will have to come off"
Hmmm this had me slightly concerned.
So I get laid down on a bed and a pretty young nurse asks me if I'd like to hold her hand (I should add I was in my mid to late 20s at this time) and with a whimper I said yes please.
As the junior doctor injected a local anaesthetic in around 10 different points around my thumb nail, which apart from hurting me even more with the needle it made absolutely no difference to the pain due to the huge amount of puss swelling my thumb, I steadied myself and then she started removing the nail.
There's a very good reason pulling nails is used in torture, its ****ing agony.
For around 10 seconds I was in so much pain as she, under the instruction of her boss, removed my thumb nail. When it came off, and she squeezed all the puss out the pain just vanished. It was brilliant.
When it grew back my thumb nail had a bumpy pattern on it that to this day, some 15-20 years later, is still there.
The junior doctor and handholding nurse were fit.
