I don't know about this. There are some physical pains that look agonizing, like whiplash. The closest thing I've had to that is a stiff neck and completely smurfs up any sniff of comfort. You can't even move without the damn thing eating at your neck again. I was going to say emotional before I gave this proper consideration but I wouldn't know because I've never experienced emotional turmoil.

Oh yeah and some diseases can also wreck you internally so there's more linkage going one way than the other
