Yes, I thought the same thing, that all people feel emotions "physically"??
I sometimes don't know why I feel a lump in my throat, a "heavy" sensation somewhere in my chest or as if there is something squeezing something inside somewhere else, but I've started looking for, and "talking" with these sensations, and it's actually really helpful when it comes to sorting out my emotions and understanding my reactions. I recommend you all to try it, especially if you are sensitive to what others say or do. It's a bit like meditation, you sit down, relax and then just "go into" the pain or the "energy clutter" you feel, and then ask it questions and answer them (through imagination, I guess) from within the "pain". It's cool. It actually answers a lot. OK. I probably sound mad again.
But try it. It's like a form of active imagination, I guess. And it's a way to access the unconscious. And yes, it DOES bring out answers. I sense such "blocks" in my body more or less all the time, and the more I talk with them, the more I relax them. When I get them "off my chest" I feel as if I can breathe freely again. In me, it doesn't even have to be big things like a heartache, it can be because of things I thought were really insignificant, and then suddenly I talk with it, and see that it was bigger than I though consciously. In a way I feel these physical things more easily than the emotions itself. OK. End of lesson one. Someone please say they tried it and it worked.
(If nothing else, you'll have a good laugh while trying...)
Edit: Btw, I'm not sure I'd call it a "pain". It's more often a cramped feeling. As if something inside me blocks the natural "flow" or something like that. I can get pretty nervous/desperate by these blocks if they grow large.
