Title: Why is pain different for different parts of the body?
Post by: Aeddan on 06/03/2021 11:20:43
The other day I hit my elbow on the wall & there was a shooting pain that lasted quite a while.
I thought to my self I could probably hit the wall with my fist with MORE force & be in less pain (not that I would ever do that).
Subbing a toe is waaay more painful than knocking a finger.
With the tattoo on my back some parts were painful. Some parts with ok & some parts there was no pain at all.
I stopped getting tattoos not because of physical pain but because the sound of the needles became too painful.
Braking bones isn't painful. Braking the T4 only left me feeling slightly winded.There was no major pain.

However . . . There is one thing that is incredibly painful ( I said one thing. Not two small rugby ball shaped things that for the life of me I cant remember what they are called ;) )
The most painful thing came from helping a friend practise piercings. I dint have any & wasn't planning on keeping anything, I just wanted to help out...by volunteering for a septum piercing.
The second the needle touched my nose tears were streaming down. The needle slipped &  went upwards. Incredible pain came from that!

But why ? Surely where I injure my self should not impact the level of pain.

Why would you not think that where you injure yourself shouldn't impact the pain you feel?
Pain is part of the body's way of protecting itself.  It's its way of saying "hey, you are damaging yourself, stop it!"
Some parts of your body, by necessity, it would want to warn you about damage more than others.  Feet, because they are so important to your locomotion, for example.  With smacking your elbow, it is a matter of hitting the  nerve bundle that carries sensory information from the hands.

I guess it's the severity of the pain from those 4-5 locations that bothers me.
Any pain changes my behaviour & get me to check everything is ok, but those few places go a bit OTT on the pain scale, with pain that lasts quite some time.
