If you haven't got one, try to get a foam roller and use it. It feels pretty much like that, without the whole being paralysed bit. They're just a hard foam cylinder you roll your back on, but it feels great. You can get them at sports stores or online.

Damn I feel this. I’ve got a spot in my neck that must be a pinched nerve because no amount of popping, stretching or massaging it is helping.
