Double jointed hips??

if i sit for awhile, or lay down flat on my back when i try to get up or even move my foot i have intense pain deep within my hip joint. even while driving, it is sometimes difficult to switch from the gas to break. could i be double jointed? also when im standing up and abduct my leg i can feel my hips pop, almost move out of socket.. this happens in both hips, but not at the same time. what could this be? any tips?
