Physical would be getting a big toenail removed. I'm pretty sure the doctor was incompetent - she went chalk white and was shaking - couldn't get the anaesthetic to take and kept injecting more and more and at one point the needle went directly through the tendon (horrendous feeling - it's not even "pain" it's a feeling I can't describe). I was suffering so much that I just said "yeah its numb now" and let her jam the metal rod under my nail, grip it with the little pliers and rip it off.
It was not numb. I just wanted it to be over

.
Emotional pain is a tough one. I shut down and go alarmingly numb quite easily and then emotional pain leaks out slowly in weird, seemingly unrelated ways for weeks or months. I can't really pinpoint a worst. To be quite honest I suspect most of it just lives in there, repressed and festering.
... .... Ho ho ho.
