At two months post op, my doc prescribed PT so as to reintroduce movement in a carefully monitored structured environment which would restore both strength and range of motion. I would consider asking for a scrip for PT so issues such as these you fear may be addressed under guidance and care. Gee whiz, every surgery I have been through which produced a post op effect as you describe was accompanied by a PT scrip, Sandy, so healing could be best possible without inducing stiffness that endures. It is a common package in these parts of the country.
Caring,
