Physical pain is easier to treat (morphine/oxy, for example). When someone you love dies or betrays you, nothing can fix it. You can go to an emergency room and get a cast that will bring someone back to you. But they can sure remedy your physical pain.
Physical. I've gone through enough emotional pain and I can say that it's definitely worse. Physical wounds heal fast. Emotional ones take a much longer time to recover from, and that's IF you ever do recover from them.
They both go hand in hand. You suffer from physical pain and the emotional response whether obvious or left more internal is just as bad. You suffer from emotional pain and you begin to hate yourself enough which leads to physical pain. Its all bad. No better or worse.
Most of men in my country work several years in military. All of my friends are discharged now. Friends who were in front lines or worked as a marine says they could endure their pain well. However friends who worked as administrative clerks always say military life was terrible.
There is research that shows that emotional pain activates similar parts of the brain that light up when you experience physical pain. That being said, I would choose physical pain (I am assuming it's pain that will heal or recover from) over emotional because I could know the extent of the damage. Emotional damage can cause long-term damage to mental health without you knowing how bad it is until it's too late.
