@Trailgirl - we all respond so differently to surgeries. It could be that some nerves or tendons have been aggravated by the surgeries. My lumbar fusion was done with an anterior approach (for the allograft; "hardware" put in from the back). While my sciatica pain is no longer an issue (yay), a couple times a week I will experience the worst itch imaginable on the bottom of my right foot! Scratching does nothing. All this to say that there are so many nerve threads and connectors going through the facet joints and other structures in the lumbar and SI regions that could have been irritated by the cleaning and work they did there which is now triggering your pain response. I would ask about a cortisone injection to calm it down, rest on the PT (I suspect you were just released to begin it?), and see how your hip responds. It might also be worth asking your OS about the possibility of some minute bit of debris from the laminectomy having migrated to start this irritation. (Note - I have no medical training at all, but have spent lots of time discussing my options and researching before getting my fusions.)
And shame of that ortho for trying to shame you for what you have needed to have done.
