I am 21, I am 5′2 and 135 lbs and I am having this hip pain that usually flares up when i am sitting for a while with my knees higher than my waste (I am trying to explain as best I can) its like it slips out of socket and i have to work it back in by walking for a while, but I cannot put much pressure on it while doing so. I am double jointed in my hips if that means anything. I am also having knee pain, when I am sitting with them bent, they cramp up. I have had the hip pain for a while and the knee pain just started. I have been to a chiro and gotten Xrays and he couldnt tell anything was wrong but there has to be. Thanks!
