I have hip pain too but I also have amazing flexibility. I have to keep my feet up or blood pools to my feet. So I sit at my desk either indian style or like right now with my feet sort of tucked under me but to one side slightly. I have to move very often or my hips will hurt later too.
When I’m not at my desk I prefer our love seat that is like a double lazy boy. I always pull the foot rest up when sitting there too.
I have exactly the same problem with chiropractors. They have told me I’m hypermobile and so I stretch too far when they are trying to get me lined up. But it feels like I’m back out of place within hours.
My husband got a video about home chiropractic and he learned many of the basic moves to keep me lined up. He knows how to get my hip back right and has to get my back almost every day.
