Having lost a Father,a Mother, three brothers, and one sister all in one night, I would have originally said emotional pain. Then taking three to the chest makes you think otherwise on the subject, but I digress. The answer to this question really depends on how one deals with pain or hurt and what they perceive as pain or hurt. And of course, the experiences a person has been through can change their answers and thoughts as well on which is greater. So, the answer is never as simple as one or the other. I myself through my experiences would say "Emotional Pain" seeing as I have recovered from physical pain that has occurred to me.
I think emotional pain is worse. I'm fine with physical pain. I almost twist my ankle, pull some muscles, hit my head HARD, whatever. I can get through it with a smile. But emotional pain? I feel like I'm being broken from the inside-out. Yes, I can hide the pain mostly behind a smile, but when I'm alone, emotional pain is what makes me bawl. When my brother yells at me for a something I've done wrong when I didn't mean to do it or tells me I'm not/never good enough... When my dad gets overly angry and screams his head off... When my mom called me a curse word for the first (and luckily only) time. I didn't mind when my brother beat me to the ground, or when my friend kicked me hard enough to rip a muscle. I cried when they said mean words.
