Eli5 Cut finger, other finger hurts as well.

145 views

I chopped the tip of my pointer finger off opening s bag. I have already promised to use scissors to open bags moving forward.

They stitched and cauterized my finger and everything is perfectly fine outside of the pain of the healing wound. That and the pain on my middle finger, a finger that has absolutely zero scratches or cuts.

It does not hurt to touch, or to use, it just has thr same pain sensation as the pointer finger with the stitches.

Can anyone explain what this is because it is truly a wild experience.

The nerve endings for your fingers are a little weird, they branch out and so the nerve endings for your pointer finger are going to go to your pointer and middle finger, and the nerves going to your ring finger are going to go to your middle finger and your pinky, your thumb is split off a little further away if I remember right so you don’t get as much referred pain there.

A few weeks back I smashed my middle finger in a fence at the dog park, it was really bad (split the mail, bled bad) and my ring finger hurt in the same spot also, even though it was not involved in the fence latch altercation.
I know the nerves can get mixed signals specifically when it comes to pain, because fingers are made to be more sensitive for touch purposes (so you can have very precise touch sensation on tips of fingers), but this can make them a bit wonky for pain reception. Almost like how a sensitive microphone picks up the extra noise when it’s close proximity, except it isn’t noise it’s pain receptor nerves firing off, giving you referred pain.
