Twitches don't hurt the horse. They his a pressure point that releases endorphins.
I wouldn't use twitching for every single thing where my horse wants to misbehave or react negatively, but for something like clipping or giving shots it could be extremely helpful. It gets the horses mind of what you are doing.
When used incorrectly is when it becomes the problem and if you don't know how to use them then you shouldn't be using them.
I don't like those twitches that are made to be able to be used by one person, they are designed funny and REALLY hard to get off in an emergency. I actually use a blanket clamp/clip to twitch myself, works awesome and is quick and easy to remove if I need too.

It's foolish to NOT do it without a twitch. Injections are in a very delicate spot and anything you can do to minimize negative reactions you do. My mare stands perfect too, doesn't mean she would when a big needle is being injected in her - even if she is sedated.
