There's a lot of nerves that refer pain elsewhere. (For example, my "ice cream headache" sensation is smack in the middle of my sternum, while for most it's in the forehead.) From an evolutionary standpoint, if "stuck" sends the message "vomit" that would most likely occur if something's stuck in the esophagus, not lower. Because of the band, the "stuck" is actually lower, but the nerve pathways and the brain interprets it in the usual way. This is speculation, but that's my guess.
And FyrEMT, my dance is to bend back, arms outstretched, stretching everything as o p e n as possible.
