Rina S please enjoy the openings. This work does not have to be painful. and upper body may have a different harmonic to it, in contrast to lower body.  Pain is not a measurement of the benefits - ever.  Honestly, as the body gets healthier it has less pain so the better way to measure is how much more ease and flow you free into.  Enjoy the journey 

Rina S Im smiling, maybe you are just improving? Pain is often the sign of tissue that has not been opened for a long time or ever. Once we do more of this work, the discomfort lessens and release is faster.  Enjoy your progress.
