Emotional by far.

Most physical pain is passing (House is an exception), but it seems more often that emotional pain will induce physical trauma, as well. I would venture a guess that emotional trauma would bug you in your sleep and in your awaking hours, while physical trauma would keep you from it, but once you get there, it's gone.

The mind also gagues physical pain based on severity, while emotional pain is there, and will get you when you least expect it. However, it is possible that old injuries will get you, also.

Now that I think about it, the two pains are very much alike, but I'd venture a guess that emotional is worse.

You can even get medicine for both, but emotional seems to counter it not by making you feel better, but by making you feel worse and making you like it.
