Measuring Pain Objectively

Apparently physical (not emotional) pain can be measured as per this article: http://io9.gizmodo.com/scientists-succeed-in-objectively-measuring-pain-472456061

Not only can pain be measured, it has also been found that the measured pain is reduced after painkiller is taken.. Interesting.

The article goes on to say that tests to determine pain quantitatively in a clinical setting are some time away.
