I had surgery to put a “rod” in my femur for bone strength. Due to the radiation of my thigh, the concern was my femur breaking with just walking. This was to insure no future breakage. I would again be on crutches but putting full body weight on my leg the next day. I chose to do physical therapy on my own this time. I did a lot of walking and water exercise to increase my leg movement & motion. Initially & for about 3 weeks, I could feel the rod in my bone. It was painful. But as it bonded to the bone, I could no longer feel it.
