Posture Pump

I got my lateral cervical film today from the chiropractor -- apparently I am lacking a proper cervical curve. So I was prescribed a posture pump device and used it a few minutes ago. I don't really feel any different although I admit it was pleasant relaxation during the exercise (I extended it from 10 to 20 minutes as a result). My neck is a little bit sore right now, and I'm sure it will take a lot more use for results. Rome was not built in a day.
