I would say yes, the healing one receives is never just on a physical level. Yes, as you get set backs and pains in the physical so shall emotions have its ups and downs. Remember it is just energy and it comes in many forms be it pain or some emotional twist. It is a label, so try not to dwell on it and see it as part of the healing process. See it for what it is and let it flush out with the cleansing of the breath.
Counteract the waves by seeking guidance, help and support from your Masters. Realize these are blessing and teachings in disguise and let them pass with love, light and compassion. Remember and reconnect with the blissful state of being you have tapped into and affirm your resolve in the direction of your choice on you path.
As Mater Lin states, stick with it and this to shall pass, or something along those lines. The good news is although it has the illusion of a set back it is in fact another step forward.
