Ok... so I wasn't the bravest kid ever. I hated shots when I was a kid. I don't remember ever 'crying' when I got a shot but my anxiety level went sky high.
As time wore on I got used to shots... and eventually I thought nothing about them... no anxiety at all... not even after some shots that actually hurt pretty badly.
Then I got older.. health problems set in, and about 4-5 years ago I went thru a series of tests where I was giving blood weekly. You would think that getting stuck so regularly I would have remained non-caring about shots and even getting MORE immune to them... but I didn't...instead, I started hating them again.
Today I only have to give blood a couple of times per year... one flu shot per year.... BUT.. I'm back to being a kid again. I hate them.
There is something to this second childhood thing.
BTW... the most painful shot I ever received was a pneumonia shot... about 3 or 4 years ago. It didn't hurt badly when I got it, a little, but later that day.. and for the next 3 blessed days.. it was agony. I couldn't use my arm.
Got a tetanus shot on my butt some years ago that was bad.. but nothing like the pneumonia shot. - JamesJM
