I'm curious...
For me, it's a tough call, I've broken multiple bones in my foot, broke my nose (jumping off a sand dune), even had a couple of kidney stones (several hours of pain)
BUT.
The most painful, I had an ingrown toe nail at about 11/12 and it got quite infected ewww, the doc was going to remove a corner of the nail, then i was just going to go home... ok so 20 years
ago now, the doc looked at it, went "hmmm" and decided it was too infected, he's simply going to remove the whole nail..
No injections.
No tablets
No pain relief ...
So he coats my toe in iodine, goes a funny shade of red/purple when painted on skin, i was watching what they did, then he tells me to lay back, so i did, and out come the heavy duty pliers and other surgical cutting tools and ..
WHOLLLLLLLLLLY FUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU
Imagine a coke can, the sound of the nail being ripped out sounded like a kid slowly pulling off a ringpull, not a quick pull, but a little bit at a time until it came out, I heard the nail ripping skin off, i felt everything, for a good 40 seconds of pain I can honestly say if there had of been more pain I think i would have passed out from the pain..
Next time you stub your toe hard and it hurts like crap, eye watering pain, take that pain and tripple it... that's how it feels yo have your big toe nail slowly ripped off without any kind of anesthetic or pain relief. - the more i think back the more i think he was incompetent.
