It feels like somebody putting barbed wire through your belly button [and] around your pelvis and they're twisting it and pulling it and all your insides are just being squeezed and sort of pushed and pulled and everything is just being twisted. And then they set fire to the barbed wire and it starts getting hot and everything's just being squished inside you basically.
It's as if somebody's driven a knife into my side, or, hammered or screwed something in and it just gets tight and I have to wait for it to pass.
