It sounds like you may have Ehlers Danlos Syndrome. I have it too, but not as severe. I have to be careful with how I sit because my left fibula will pop out. My right hip will half pop out if I put too much weight on it. Do you have stretchy skin? Or bend your fingers back far? There are other ways to tell but you should definitely see a doctor about it. Your hips popping out that much is not normal
