About a month ago I broke my femur. (39 Male)
I was being foolish as I was skateboarding in the house, but wasn't going that fast. Anyway, I hit a rubber bump that separates the kitchen and the living room and next thing I know, the board is flying and I am falling. When I hit the floor, I was in the most painful agony I have ever felt in my life. Screaming at the top of my lungs.
I had instantly broken my upper femur, as soon as I fell. Normally it takes a car accident to break your femur. I later Googled it, and yes.. PV does cause weak bones. So Be Careful! If you ski, you are walking a thin line. I know I will be way more careful from now on! It's been about a month and I now have a metal rod In my thigh, and some nails. Should be interesting going through TSA!
