I see you mentioned about a cusion I think it be a good idea to see if you can get one to provide the right support in your chair

I saw a video from Gem, heels on wheels, and she had her seat tilt altered and it helped with her hip pain. So I tried it, it worked really well. I have FAI and CAM impingement, labral tears with associated cysts, bursitis, tendonitis, tendonosis, osteoarthritis and meralgia paresthesia bilaterally, so it might help you. When I say seat tilt my bum is lower than my knees? Does that make sense? I got my chair from wheelchair services as did my daughter.

What kind of cushion do you currently have? I use a Roho because of past pressure sores but some people can find them unstable, especially depending how your chair is set up. My chair has lots of lateral support so I don’t find it too wobbly. Other common types I know of are Jay cushions, invacare matrix, supracor, plus just your basic memory foam type ones, but they should definitely never be used if you are a full time chair user!
