Went back to the doc yesterday about my back. He adjusted the rotated hip and we talked about what's causing it. It's been almost a year and the answer is, we don't know.
It's not chronic since I can go for a couple of weeks without the hip rotating. There doesn't seem to be an exact movement that rotates the hip other than I know when it's happened. It can be as simple as rolling over in bed to another position. Bending down to get something. Lifting a gallon of milk off the counter to put it back in the fridge. Walking a couple of blocks. Getting in/out of the car. Standing and talking to a friend. Coughing/sneezing.
What doesn't help is that all the muscles around the hip and back are connected so if the hip rotates, it takes several muscles with it causing a domino reaction.
I wonder if I need some deep physical therapy that my crappy county hospital can't give to strengthen the muscles.
Now that I have a cold, I know I'll have to be back in a couple of days to fix the hip.
It just sucks having to pay 20 bucks to put my hip back to where it should every couple of weeks.
