Why do shots feel different for different people?

688 views

When I get any kind of shot or vaccination they always say it’ll just feel like a pinch, but for me I can feel whatever is being pushed into my arm and it’s horrible. When I got a flu shot with my mother she said that it only feels like a pinch for her, nothing else. Why does this happen?

Some people are just tougher. Or maybe they don’t take the “just a pinch” literally.

I can always feel the poke, sometimes the slide of the needle, and sometimes the goo going into my arm, and sometimes the removal of the needle. I’ve never had a shot that lasted more than a few seconds, so it’s easy to such up the momentary ouch.

Sometimes the goo is just filling a space, so there’s a little pressure. Sometimes there’s a perceived or real change in temperature. Sometimes whatever it is gets a little disagreeable and can seem to burn.

The bulk of that is briefly uncomfortable, and usually returns to normal really quickly. If there’s any lasting impact, it’s usually an ache, like I bumped into something or lifted something too heavy or for too long.

Rarely, but it happens, that initial jab is less than careful, and it’s a definite, but small, stabbing pain. It, too, will subside quickly.

I’ve received hundreds of pokes for injections or blood tests by now. The worst were in the assembly lines in school as a kid, or maybe in basic training. But they still only lasted a few seconds.

Anyone should be able to handle a few seconds of horrible that doesn’t usually lead to permanent damage.
