Well, I've never been in enough of either for it to be REALLY scarring. The worst physical pain I've been in has been from snapping my collarbone (long story), and throwing my back out (no, I'm not an old granny, I just have problems like that). Both KILLED. Actually, the funny thing was, even though I broke my collarbone badly, it was the back thing that actually hurt more. And the worst emotional pain I've been in is tied between the day my mom told me my dog had three weeks to live (pancreas cancer), and the day we had to put her to sleep (like, 7 months later, damn doctors!). And it still hurts to think about that (it only happened a few months ago). So I'd say emotional pain. The physical pain hurts (maybe) worse when it acutally happens, but fades. The emotional pain takes a longer time to heal, and it gets better very slowly.
