For the past year or so, I ve come to realize that everytime I lift my right leg and then put it down, my hip pops. It feels almost like the ball and socket joint is loose or something. It doesn t usually hurt though. But i could lift my leg up and down over and over and its just goes pop pop pop pop pop. I ve asked my mom and all of my friends if theirs pops like that and only one friend can do that too, but not as frequently as mine. Is it a rare girl thing with our hips or does it happen to a lot of people???
