Learn something new everyday.....

The reason local anesthetic can really hurt some people and not even be felt in others? 

pH

How different the pH of the anesthetic is vs the tissue it's being injected into will determine how much it burns as its going in. Also for how well it will work too. I know i'm a wimp with needles, but at least this semi-explains why the local burns so freaking much (i'd never had one before Canada)........
