SCREW THAT!!! A splinter under the nail is like cutting my achilles... MAN DOWN!!! MAN DOWN!!
When I was framing houses one of those lovely splinters would manage to get under the nail... Yes I admit, I held back the tears... But damn it!! I did everything I could to get that thing out of there! The worst slivers have to be from pressure treated wood. They fester up and get nasty real quick.
So ya, when it comes to nail pain, one person might call it a 1 in pain and I would call it a 50... LOL
Wait, someone is stabbing needles in the end of your finger... I'M OUT!!!
