HI, my mother is 86 years old with a history of fractured hip that required 2 surgeries. After the first, the device came up through the head of the femur so she had a total hip replacement. That was about 7 years ago. Lately, she began complaining of pain in her outer thigh mid way down from hip. It does not hurt when lying down, but is severe when walking. Is this something I should pursue . she saw her family doctor who felt it was strain. Then I had to take her to the ED for pain. They said to take pain mess and apply heat, but nothing helps.
