Mine is killing me again lately. I also fell, my bum hitting the edge of a concrete step and a heavy upholstered chair fallilng on my leg. I think that injured another area of my back, low sacral area, and overextended my knee. I hurt and feel like one exposed nerve from hip and bum to thigh and calf and to ankle and toes and my knee is a mess. I guess at least it's all the same leg. lol
