My pain started on the left femur bone , then the whole side of my femur started hurting,then it also started hurting on the top of my thigh into me knee and down the front of my lower leg. It stops at my ankle. Now also my left arm tingles from my 3 last fingers under my arm to my sholder, and now my lower back from my spine to the left side. It started in Feb. This year, very,very painful. It hast changed at all, I've had x-rays and a bone scan so far and only some arthritis.
