This is what I also have: 49 years old and femaie.
Had xray last week, Internal med doc can see something in the hip joint where my leg enters hips. He took xray over to radiologist at the hospital while I waited. He said either early artritis or some sort of injury that may need surgery to repair. He said take 2 advil or aleve at night for 2 weeks and call him with results. If advil helps its artritis.
